duchenne:7752004 | Dysmorphic features in patients with complex glycerol kinase deficiency. | [
"Complex glycerol kinase deficiency is a contiguous gene syndrome consisting of a deletion of the glycerol kinase locus, together with the genes for adrenal hypoplasia congenita or Duchenne muscular dystrophy or both. We describe an infant with complex glycerol kinase deficiency and mildly dysmorphic features similar to those seen in other patients, including an \"hourglass\" appearance of the middle of the face; hypertelorism; rounded palpebral fissures; esotropia; wide, flattened earlobes; and a downturned mouth. The combination of medical history and characteristic facies should prompt the request for specific laboratory tests diagnostic for this potentially treatable condition."

"Three patients with Duchenne muscular dystrophy presenting with failure to thrive in infancy are described. Their families noted poor growth and sought medical advice up to six months before the diagnosis was suspected. Growth charts showed weight loss between 4 and 18 months of age. Length growth was affected while growth in head circumference remained unaffected. No causes of failure to thrive were found at presentation. Failure to thrive in Duchenne muscular dystrophy has been described previously but it is neither widely recognised nor understood. Poor growth in the first years and eventual short stature, however, is a well described feature of Duchenne muscular dystrophy. Failure to thrive in our three patients may be an extreme manifestation of this."

duchenne:7573761 | A carrier of Duchenne muscular dystrophy with dilated cardiomyopathy but no skeletal muscle symptom. | [
"A 29-year-old female developed dilated cardiomyopathy at 20 years of age but with no muscle symptoms. Her 2-year-old son with Duchenne muscular dystrophy (DMD)_had no demonstrable deletion in the dystrophin gene, but all fibers except for 5% 'revertant' fibers in a muscle biopsy specimen had no dystrophin. Both skeletal and cardiac muscle biopsy specimens from the mother showed a mosaic distribution of dystrophin-positive and -negative fibers, and so she was diagnosed as being a manifesting carrier of DMD. We conclude that, when one encounters a female patient with idiopathic cardiomyopathy with a high serum creatine kinase level, the suspicion of her being a manifesting DMD carrier should be ruled out."

duchenne:7723955 | Genetic and biochemical normalization in female carriers of Duchenne muscular dystrophy: evidence for failure of dystrophin production in dystrophin-competent myonuclei. | [
"We studied 19 symptomatic female carriers of the Duchenne muscular dystrophy (DMD) gene. Most of these dystrophinopathy patients had had an erroneous or ambiguous diagnosis prior to dystrophin immunofluorescence testing. We assessed clinical severity by a standardized protocol, measured X-chromosome inactivation patterns in blood and muscle DNA, and quantitated the dystrophin protein content of muscle. We found that patients could be separated into two groups: those showing equal numbers of normal and mutant dystrophin genes in peripheral blood DNA (\"random\" X-inactivation), and those showing preferential use of the mutant dystrophin gene (\"skewed\" X-inactivation). In the random X-inactivation carriers, the clinical phenotype ranged from asymptomatic to mild disability, the dystrophin content of muscle was > 60% of normal, and there were only minor histopathologic changes. In the skewed X-inactivation patients, clinical manifestations ranged from mild to severe, but the patients with mild disease were young (5 to 10 years old). The low levels of dystrophin (< 30% on average) and the severe symptoms of the older patients suggested a poor prognosis for those with skewed X-inactivation, and they all showed morphologic changes of dystrophy. The random inactivation patients showed evidence of biochemical \"normalization,\" with higher dystrophin content in muscle than predicted by the number of normal dystrophin genes. Seventy-nine percent of skewed X-inactivation patients (11/14) showed genetic \"normalization,\" with proportionally more dystrophin-positive nuclei in muscle than in blood. In 65% of the skewed X-inactivation patients, dystrophin was not produced by dystrophin-positive nuclei; an average of 20% of myofiber nuclei were genetically dystrophin-positive but did not produce stable dystrophin. Biochemical normalization seems to be the main mechanism for rescue of fibers from dystrophin deficiency in the random X-inactivation patients. In the skewed X-inactivation patients, genetic normalization is active, but production failure of dystrophin by dystrophin-normal nuclei may counteract any effect of biochemical normalization. In the skewed X-inactivation patients, the remodeling of the muscle through cycles of degeneration and regeneration led to threefold increase in the number of dystrophin-competent nuclei in muscle myofibers (3.3 +/- 4.6), while dystrophin content was on the average 1.5-fold less then expected (-1.54 +/- 3.38). Our results permit more accurate prognistic assessment of isolated female dystrophinopathy patients and provide important data with which to estimate the potential effect of gene delivery (gene therapy) in DMD."

duchenne:7781237 | [Complete deficiency of adhalin (50 kDa DAG) in skeletal muscle of malignant limb-girdle muscular dystrophy]. | [
"Malignant limb-girdle muscular dystrophy was first described by Miyoshi and co-workers in 1966, and has clinical features similar to Duchenne muscular dystrophy but is inherited through an autosomal recessive trait. This paper describes a patient with malignant limb-girdle muscular dystrophy with complete deficiency of adhalin (50 kDa dystrophin-associated glycoprotein (DAG)) in skeletal muscle. The patient was an 11-year-old Japanese girl whose parents were cousin. She learned to walk at one year and 3 months of age. Her gait became unsteady at 3 years of age, and motor dysfunction in the lower extremities progressed thereafter. At 8 years of age, she had difficulty in standing up from a sitting position, but could walk without assistance. At 11 years, she could walk with support, but could not stand up without assistance. Her intelligence was normal. Muscle atrophy was not apparent due to obesity, but her calves appeared hypertrophic. She had generalized muscle weakness, predominantly in the pelvic girdle muscle. Muscle tone was slightly hypotonic, and deep tendon reflexes of the legs were absent or hypoactive. Her sensory system appeared normal. Serum creatine kinase level was elevated to 30 times above the upper limit of the normal range in the patient and normal in her parents. EMG showed a mild myopathic pattern. CT scan of muscle revealed marked low density in the upper legs and mild in the lower legs. Muscle histology showed muscle fiber necrosis with a small number of regenerating fibers. Opaque fibers were occasionally observed, but not as many as in Duchenne type. Fiber splitting was seen frequently.(ABSTRACT TRUNCATED AT 250 WORDS)"

"We report on the first patient identified with myotonic dystrophy and Duchenne muscular dystrophy (DMD). The family of the propositus had a strong history of myotonic dystrophy, and there was an intrafamilial pathological expansion of the responsible CTG repeat between the mildly affected mother (160 repeats; normal 27 repeats) and her more severely affected son (650 repeats), and his sister (650 repeats). The propositus was an isolated case of Duchenne muscular dystrophy with marked dystrophin deficiency in muscle biopsy. The patient was still ambulatory post age 16. Myotonic dystrophy could interfere to some extent with the progression of Duchenne dystrophy. However, other interpretations are possible. Twelve percent of dystrophin revertant fibers as observed by immunohistochemistry could be sufficient to ameliorate typical DMD clinical severity, or the patient may present a somatic mosaic. The pathophysiological interactions of these two unlinked disorders are discussed at the clinical and histopathological levels."

"Since the 14kb human Duchenne muscular dystrophy (DMD) cDNA was cloned and its protein product \"dystrophin\" was discovered, immunochemical, biochemical and genetic analyses of dystrophin (dystrophin testing) have provided an accurate diagnosis of DMD/Becker muscular dystrophy in the clinical field. We performed dystrophin testing for a 5-year-old boy and confirmed he had severe BMD. Multiplex PCR of the DMD gene showed in-frame type deletion from exon 45 to 48. Immunohistochemical analysis of the muscle specimen obtained from the patient showed a discontinuous and patchy staining pattern, using monoclonal antibody that recognizes the C-terminus domain of dystrophin. On immunoblot analysis, we detected a faint band of 390 kDa. Dystrophin quantity was less than 10% of that compared to normal controls. The correlation between clinical severity and dystrophin testing was discussed."

"We report a rare case of a female newborn presenting with muscular hypotonia, pneumonia, and cardiovascular and renal insufficiency. Adrenal insufficiency was diagnosed clinically and proven by extremely low cortisone (0.4-0.8 microgram/dl) and high ACTH plasma levels. Myopathy was diagnosed clinically, as well as by muscular biopsy. DNA analysis of both X chromosomes showed no abnormality in the region of the genes for adrenal hypoplasia and Duchenne muscular dystrophy.

"Sixty-four muscle biopsies obtained from patients with Duchenne muscular dystrophy, limb-girdle dystrophy, congenital muscular dystrophy, or who referred for diagnosis were examined with histochemical methods for dystrophin staining with antidystrophin antibodies. Six atypical cases in whom the dystrophin expression was inconsistent with both clinical and morphopathological pattern were selected: one case of Duchenne muscular dystrophy in whom dystrophin was partially represented, one case referred for investigation in whom dystrophin was absent, despite the lack of clinico-morphological signs supporting the diagnosis of Duchenne disease, two cases of congenital muscular dystrophy in whom dystrophin was absent and one patient with the same diagnosis in whom dystrophin was present, but quantitatively reduced. A patient with limb-girdle muscle dystrophy, in whom immunohistochemical investigation was necessary for the diagnosis is also reported. In conclusion, the immunohistochemical investigation using antidystrophin labelled antibodies of muscle biopsies obtained from patients with various types of muscular dystrophy is mandatory."

duchenne:7484098 | Polymerase chain reaction fiber analysis and somatic mosaicism in autopsied tissue from a man with Duchenne muscular dystrophy. | [
"Single muscle fibers, obtained at autopsy from a 22-year-old man with Duchenne muscular dystrophy were examined immunocytochemically and also using polymerase chain reaction (PCR). Dystrophin-positive cells were widespread in skeletal, cardiac, smooth muscle, and in brain cells. PCR and Southern blot analyses of DNA from peripheral blood lymphocytes revealed a deletion of exon 45 in the dystrophin gene. With PCR of single fibers, three bands corresponding to exons 44, 45, and 47 were present in the normal control muscle fibers and dystrophin-positive fibers from the patient, while only two bands, exons 44 and 47, were observed in dystrophin-negative fibers. Therefore, in this patient, the genotype of dystrophin-positive fibers differed from that of the dystrophin-negative fibers, possibly because of a somatic mosaicism for deletion in the dystrophin gene. A mutation of the dystrophin gene may have occurred in one cell at an early stage of ontogenesis."

duchenne:7955386 | Congenital adrenal hypoplasia, Duchenne muscular dystrophy, and glycerol kinase deficiency: importance of laboratory investigations in delineating a contiguous gene deletion syndrome. | [
"We describe an infant with adrenal insufficiency who was subsequently diagnosed with Duchenne muscular dystrophy (DMD) and hyperglycerolemia due to glycerol kinase deficiency. Karyotyping showed a deletion on the short arm of the X chromosome (p21.1 to p22.1). Molecular mapping revealed that the deletion extended from the 3' end of the DMD gene to a site telomeric to the loci for X-linked congenital adrenal hypoplasia and glycerol kinase deficiency. These results are diagnostic for an Xp21 contiguous gene deletion syndrome--so named because the deletion manifests as a distinctive cluster of otherwise unrelated single-gene disorders in the same individual. The Xp21 syndrome should be considered in any infant with adrenal insufficiency. Measurement of serum triglycerides (without glycerol blanking) and creatine kinase activity are simple screening tests that may facilitate early diagnosis and appropriate genetic counseling about risks of recurrence in subsequent offspring."

duchenne:7942846 | A new nonsyndromic X-linked sensorineural hearing impairment linked to Xp21.2. | [
"X-linked deafness is a rare cause of hereditary hearing impairment. We have identified a family with X-linked dominant sensorineural hearing impairment, characterized by incomplete penetrance and variable expressivity in carrier females, that is linked to the Xp21.2, which contains the Duchenne muscular dystrophy (DMD) locus. The auditory impairment in affected males was congenital, bilateral, profound, sensorineural, affecting all frequencies, and without evidence of radiographic abnormality of the temporal bone. Adult carrier females manifested bilateral, mild-to-moderate high-frequency sensorineural hearing impairment of delayed onset during adulthood. Eighteen commercially available, polymorphic markers from the X chromosome, generating a 10-15-cM map, were initially used for identification of a candidate region. DXS997, located within the DMD gene, generated a two-point LOD score of 2.91 at theta = 0, with every carrier mother heterozygous at this locus. Recombination events at DXS992 (located within the DMD locus, 3' to exon 50 of the dystrophin gene) and at DXS1068 (5' to the brain promoter of the dystrophin gene) were observed. No recombination events were noted with the following markers within the DMD locus: 5'DYS II, intron 44, DXS997, and intron 50. There was no clinical evidence of Duchenne or Becker muscular dystrophy in any family member. It is likely that this family represents a new locus on the X chromosome, which when mutated results in nonsyndromic sensorineural hearing loss and is distinct from the heterogeneous group of X-linked hearing losses that have been previously described."

duchenne:7833192 | Dilated cardiomyopathy and the dystrophin gene: an illustrated review. | [
"Cardiomyopathy is often found in patients with Duchenne and Becker muscular dystrophy, which are X linked muscle diseases caused by mutations in the dystrophin gene. Dystrophin defects present in many different ways and cases of mild Becker muscular dystrophy have been described in which cardiomyopathy was severe. Female carriers of Duchenne muscular dystrophy can develop symptomatic skeletal myopathy alone or combined with dilated cardiomyopathy. They can also develop dilated cardiomyopathy alone. X linked dilated cardiomyopathy has been found in association with dystrophin defects. The relation between the molecular defects and the cardiac phenotypes has not yet been established. New mutations in the dystrophin gene are common and such mutations cause one third of the cases with Duchenne and Becker muscular dystrophy. This means that sporadic cases of cardiomyopathy caused by dystrophin defects are likely. This paper reports such a case in a boy of 14 who died of dilated cardiomyopathy. Before the cardiac investigation, which was performed one month before he died, he had not complained of muscular weakness. He had minor signs of limb girdle myopathy and slightly increased concentrations of serum creatine kinase. He was found to have an unusual deletion in the dystrophin gene."

duchenne:7936290 | Amino-terminal deletion of 53% of dystrophin results in an intermediate Duchenne-Becker muscular dystrophy phenotype. | [
"We report a Japanese boy with muscular dystrophy whose clinical symptoms were intermediate between those usually considered typical of Duchenne and Becker muscular dystrophies. The patient had a large inframe deletion extending from exons 3 to 41 of the dystrophin gene, which would be expected to cause the production of a dystrophin protein composing only 53% of the normal polypeptide chain. Such an inframe deletion would be expected to cause Becker muscular dystrophy. We did not obtain evidence for alternative splicing or for RNA editing. Immunocytochemical analysis of skeletal muscle showed that a dystrophin-related polypeptide was detectable with antibody directed against the carboxyl-terminal part of the polypeptide but not with antibodies directed against the amino-terminal part, although labeling by antibody against the carboxyl-terminal was faint and patchy. The severity of the disease in this case may be due to the lack of the amino-terminal, actin-binding domain of dystrophin."

duchenne:7802009 | Additional case of female monozygotic twins discordant for the clinical manifestations of Duchenne muscular dystrophy due to opposite X-chromosome inactivation. | [
"A pair of female monozygotic (MZ) twins, heterozygous carriers for a deletion in the DMD gene and discordant for the clinical manifestations of Duchenne muscular dystrophy, were analyzed by molecular studies, in situ hybridization, and methylation pattern of X chromosomes to search for opposite X inactivation as an explanation of their clinical discordance. Results in lymphocytes and skin fibroblast cell lines suggest a partial mirror inactivation with the normal X chromosome preferentially active in the unaffected twin, and the maternal deleted X chromosome preferentially active in the affected twin. A review shows that MZ female twins discordant for X-linked diseases are not uncommon. Twinning and X inactivation may be interrelated and could explain the female twins discordant for X-linked traits."

duchenne:8069990 | Succinylcholine-induced cardiac arrest in children with undiagnosed myopathy. | [
"Two paediatric cases are reported in which unexpected, life-threatening arrhythmias occurred. Routine induction of general anaesthesia with thiopentone, 5 mg.kg-1, in one and with halothane in the other, and succinylcholine 1.25-1.5 mg.kg-1 i.v. was followed by the development of wide complex tachyarrhythmia with hypotension in the first case and asystole in the second case despite pre-treatment with atropine in both cases. The first patient was resuscitated with tracheal intubation, 100% oxygen, manual ventilation and intravenous lidocaine and bicarbonate. The second patient required intubation, manual ventilation, 12 min of CPR and i.v. calcium, epinephrine and bicarbonate, as well as DC counter shock. Neither patient received dantrolene. Early recovery in both patients was uneventful with no neurological sequelae. Subsequent investigations revealed the presence of a dystrophin-deficient muscular dystrophy, Duchenne muscular dystrophy and Becker muscular dystrophy respectively, previously unsuspected, in both patients. The aetiology of the observed arrhythmias was presumably hyperkalaemia, secondary to succinylcholine-induced rhabdomyolysis. It is suggested that when faced with sudden, life-threatening arrhythmias following succinylcholine at induction of anaesthesia for paediatric patients, clinicians should include occult myopathy in the differential diagnosis, and thus consider the aggressive management of hyperkalaemia in addition to basic resuscitative efforts."

duchenne:8068162 | Chronic respiratory failure in limb-girdle muscular dystrophy: successful long-term therapy with nasal bilevel positive airway pressure. | [
"Chronic respiratory failure is a major factor contributing to mortality in progressive neuromuscular disorders. Among the muscular dystrophies, respiratory failure most commonly occurs with Duchenne dystrophy, while in Becker, limb-girdle, and facioscapulo-humeral dystrophies, respiratory failure is infrequent and generally occurs in the more severe cases that have progressed to a nonambulatory, advanced functional stage. We report two brothers with a myopathic disease in which the distribution of weakness, initial clinical course, heredity, and muscle pathology most closely resembled a limb-girdle type of dystrophy. Both brothers, however, presented with chronic alveolar hypoventilation and respiratory failure when their locomotor disabilities were still mild. Respiratory failure was reversed, and satisfactory ventilation has been maintained for more than a year using a type of non-invasive intermittent positive pressure ventilation, with a bilevel positive airway pressure device (Bi-PAP), administered through a nasal mask during sleeping hours. These cases demonstrate an unusual presentation of limb-girdle dystrophy, and document that nocturnal, nasal administration of continuous airway pressure using the Bi-PAP device may be sufficient to maintain adequate long-term ventilation in some patients with neuromuscular causes of respiratory failure, and thus significantly improve quality of life and delay the need for more complex or invasive forms of assisted ventilation."

duchenne:8033374 | Gene deletion causing adrenal hypoplasia congenita and hypogonadotrophic hypogonadism. | [
"We report a patient with X-linked adrenal hypoplasia congenita and hypogonadotrophic hypogonadism in whom there were no clinical or biochemical features of either glycerol kinase deficiency or Duchenne muscular dystrophy. (The adrenal hypoplasia congenita and glycerol kinase loci map in Xp21 distal to Duchenne muscular dystrophy, and proximal to DXS727). DNA isolated from our patient was analysed by PCR amplification with primers for appropriate loci in the Xp21 region. This analysis revealed the absence of DXS319, which lies near the adrenal hypoplasia congenita deletion critical region, and the presence of DXS727, which is distal to the gene. The absence of glycerol kinase deficiency biochemically and clinically was consistent with the presence of one glycerol kinase exon product from PCR primers P17/P18 which lies within the glycerol kinase gene. The hypogonadotrophic hypogonadism is universally found in X-linked adrenal hypoplasia congenita and is thought to be pituitary in origin. These findings suggest that a gene locus resulting in hypogonadotrophic hypogonadism is present in the Xp21 region and is an integral part of the adrenal hypoplasia congenita gene or in close relationship to it."

duchenne:8064304 | Assessment of the 50-kDa dystrophin-associated glycoprotein in Brazilian patients with severe childhood autosomal recessive muscular dystrophy. | [
"Recently, we have demonstrated the specific deficiency of the 50-kDa dystrophin-associated glycoprotein (50DAG) in severe childhood autosomal recessive muscular dystrophy with Duchenne-like phenotype (SCARMD or AR-DLMD), a disease first reported in Tunisia and now presumed to be prevalent in North Africa and the Middle East. Here we demonstrate the deficiency of the 50DAG in one caucasoid and 5 negroid Brazilian patients with severe muscular dystrophy, which confirms that AR-DLMD with the 50DAG deficiency is not confined to the Arab populations. Without the analysis of both dystrophin and 50DAG, isolated male patients with this condition could be undiagnosed or misdiagnosed as having Duchenne or severe Becker muscular dystrophy. We also report, for the first time, the normal expression of the 50DAG and other dystrophin-associated proteins in one negroid and 2 caucasoid Brazilian patients with a phenotype indistinguishable from that of AR-DLMD with 50DAG deficiency. This is consistent with the genetic heterogeneity for the phenotype of AR-DLMD."

duchenne:8012192 | Deficiency of the 50 kDa dystrophin-associated glycoprotein and abnormal expression of utrophin in two south Asian cousins with variable expression of severe childhood autosomal recessive muscular dystrophy. | [
"Two male cousins with severe childhood, autosomal recessive, Duchenne-like, muscular dystrophy (SCARMD) have been identified with a deficiency of the 50 kDa dystrophin-associated glycoprotein but normal expression of dystrophin. Both boys were from consanguineous marriages and were Asian, having originated from Pakistan. This is in contrast to all previously reported cases from North Africa. Clinical severity varied and the patients were still able to walk at 13 and 12 yr, respectively. Neither had calf hypertrophy, a feature reported to be almost consistent in the North African patients. Abnormal expression of utrophin, the dystrophin-related protein, was observed on the surface of several non-regenerating muscle fibres, with less intense immunolabelling in the clinically more affected child. This family shows that SCARMD is not confined to North Africa and illustrates a hitherto unreported expression of utrophin in this condition."

duchenne:7827443 | Complex genetic counseling and exclusion of Duchenne muscular dystrophy in a twin pregnancy after in vitro fertilization (IVF). | [
"A twin pregnancy following in vitro fertilization-embryo transfer coincidentally at risk for the X-linked recessive Duchenne muscular dystrophy is described. First-trimester prenatal diagnosis by transabdominal chorionic villus samplings on the dichorionic placentae and molecular linkage analysis could exclude the disorder in both fetuses. Genetic counseling and prenatal diagnosis were particularly complex due to the twin pregnancy, the need for linkage analysis, and confined placental mosaicism 45,X/46XX in one of the fetuses. All parties should be aware that additional invasive diagnostic procedures in the second trimester might be required. It is proposed that, in similar situations, only one, arguably two, fertilized egg be transferred at a time to facilitate prenatal diagnosis and decision making for these rare couples. This problem, however, may be increasingly overcome by preimplantation diagnosis."

duchenne:8209894 | Restoration of half the normal dystrophin sequence in a double-deletion Duchenne muscular dystrophy family. | [
"Two male cousins with Duchenne muscular dystrophy were found to have different maternal dystrophin gene haplotypes and different deletion mutations. One propositus showed two noncontiguous deletions--one in the 5', proximal deletional hotspot region, and the other in the 3', more distal deletional hotspot region. The second propositus showed only the 5' deletion. Using multiple fluorescent exon dosage and fluorescent multiplex CA repeat linkage analyses, we show that the mother of each propositus carries both deletions on the same grandmaternal X chromosome. This paradox is explained by a single recombinational event between the 2 deleted regions of one of the carrier's dystrophin genes, giving rise to a son with a partially \"repaired\" gene retaining only the 5' deletion."

duchenne:8279470 | A novel point mutation (G-1 to T) in a 5' splice donor site of intron 13 of the dystrophin gene results in exon skipping and is responsible for Becker muscular dystrophy. | [
"The mutations in one-third of Duchenne and Becker muscular dystrophy patients remain unknown, as they do not involve gross rearrangements of the dystrophin gene. We now report a defect in the splicing of precursor mRNA (pre-mRNA), resulting from a maternally inherited mutation of the dystrophin gene in a patient with Becker muscular dystrophy. This defect results from a G-to-T transversion at the terminal nucleotide of exon 13, within the 5' splice site of intron 13, and causes complete skipping of exon 13 during processing of dystrophin pre-mRNA. The predicted polypeptide encoded by the aberrant mRNA is a truncated dystrophin lacking 40 amino acids from the amino-proximal end of the rod domain. This is the first report of an intraexon point mutation that completely inactivates a 5' splice donor site in dystrophin pre-mRNA. Analysis of the genomic context of the G-1-to-T mutation at the 5' splice site supports the exon-definition model of pre-mRNA splicing and contributes to the understanding of splice-site selection."

duchenne:8199594 | Identification of a point mutation and germinal mosaicism in a Duchenne muscular dystrophy family. | [
"Duchenne and Becker muscular dystrophies (DMD and BMD) are allelic X-linked disorders arising from mutations in the (2.4 Mb) dystrophin gene at Xp21. We have applied the reverse transcriptase-polymerase chain reaction (RT-PCR) to identify a larger than normal dystrophin mRNA from a male with Duchenne muscular dystrophy and his younger affected brother. The increased size of the dystrophin mRNA was due to a splice-site mutation at the exon 26:intron 26 junction where a T to G substitution prevented normal RNA processing. A cryptic splice-site, downstream of the mutation, was activated during processing, resulting in the inclusion of 117 bases of intron 26. This insertion introduced an in-frame stop codon into the mature dystrophin mRNA. An allele-specific test was developed to identify the mutation and was applied to this family. Interestingly, the mother of the two affected boys did not carry the mutation, as determined by allele-specific amplification and direct DNA sequence analysis, indicating gonadal mosaicism. Her eldest daughter, designated as a carrier based upon conventional testing and haplotype analysis, also did not carry the family mutation. Initial haplotyping of the family appeared to be straightforward with gonadal mosaicism becoming evident only after allele-specific analysis. The application of linked markers to identify the disease allele for conventional genetic counselling would have been erroneous in this family and highlights the diagnostic power of precise identification of the disease-causing mutation."

"Glycerol kinase deficiency occurs either as a relatively benign isolated enzyme deficiency, or as part of a syndrome resulting from a microdeletion in the p21 region of the X chromosome associated with congenital adrenal hypoplasia and/or Duchenne muscular dystrophy. Developmental delay is a consistent feature of the microdeletion syndrome but not of the isolated enzyme defect. We report a case of isolated glycerol kinase deficiency in a neonate presenting with hypotonia, apnea, mild developmental delay, and glyceroluria, without evidence of adrenal insufficiency or myopathy. A mild communicating hydrocephalus was noted on magnetic resonance imaging brain scan. It is important, therefore, to exclude glyceroluria in infants being investigated for apnea and hypotonia."

duchenne:8291533 | Isolation of a yeast artificial chromosome contig spanning the X chromosomal translocation breakpoint in a patient with Rett syndrome. | [
"Rett syndrome is a neurodevelopmental disorder observed exclusively in females. A de novo X;3 translocation was detected in a patient (TH) with Rett syndrome. The X chromosomal breakpoint maps to Xp21.3 between the distal end of the Duchenne muscular dystrophy (DMD) gene and the DXS28 (C7) locus. To determine if this translocation caused the Rett syndrome in this patient, our efforts focused on mapping and cloning of the X chromosomal breakpoint in this patient. Toward these goals, we generated a set of radiation-reduced hybrid cell lines for the short arm of the X chromosome to use as a source for region-specific markers. Using Alu-PCR, 13 new DNA markers were isolated from a radiation-reduced hybrid, which retained both DMD and DXS28. These markers were localized within Xp21 using DNA from males with various interstitial deletions in this region. Two new markers, K23-2p and K23b-1, were found to be closer flanking markers to the X chromosomal breakpoint than DMD and DXS28. Long range restriction mapping using K23-2p and K23b-1 determined that the maximum distance between them was 800 kb. Several of the new markers were developed into sequence tagged-sites and were used to isolate yeast artificial chromosome (YAC) clones. A total of 22 YAC clones was isolated and characterized; these YACs were then developed into 3 large contigs in the Xp21.3 region.

duchenne:8413368 | Molecular analysis of the Duchenne muscular dystrophy gene in patients with Becker muscular dystrophy presenting with dilated cardiomyopathy. | [
"Molecular analysis of the Duchenne muscular dystrophy (DMD) gene was performed on 4 unrelated patients with Becker muscular dystrophy (BMD) presenting with dilated cardiomyopathy. Two patients with a deletion involving exon 1 were quite unique in that they developed fatal myocardial involvement in their teens, despite the absence of significant muscular weakness. The deletion found in these patients comprised the 3'-end of exon 1 and the greater part of intron 1. Two other patients with a deletion of exon 47 showed progressive muscular atrophy and weakness; they were considered to be typical BMD in both clinical features and the type of gene deletion. We speculate that a deletion around exon 1 may severely damage the expression and/or the function of dystrophin selectively in cardiac muscle, but not in skeletal muscle."

duchenne:8307658 | Quantitative analysis of dystrophin gene amplification products using a PC-based image analysis system. | [
"A PC-based image analysis system for gel photographs of DNA gel patterns was developed. It was originally designed as a general-purpose, low-cost, yet high-performance system for wide applications in the biomedical area. In this study, we performed analysis of gel images obtained by polymerase chain reaction (PCR) amplification. The system employs a high-resolution CCD camera that can accurately measure grayness of the gel photographs for quantitative analysis of PCR products. The target DNA (exon 52 of the dystrophin gene), which had been found to be deleted in some patients with Duchenne/Becker muscular dystrophy (DMD/BMD), was amplified for the female family members together with the control DNA (exon 60) as a reference. The ratio of the target DNA to the control DNA was determined from PCR products to identify the carrier status of this disease by means of gene dosage. We conclude that 'the PC-based image analysis system' was useful for quantitative deletion analysis of DMD/BMD heterozygotes."

All had negative configurations on scotopic electroretinograms showing a reduced-amplitude B wave in the dark-adapted state.",
"Our original report suggested a diagnosis of Aland Island eye disease, which appears to be an incomplete form of congenital stationary night blindness. Linkage data place Aland Island eye disease and congenital stationary night blindness at Xp11, whereas our patients had deletions at Xp21. The phenotype reported here may represent the effects of a single gene defect or the compound effects of the Xp21 contiguous gene syndrome (complex glycerol kinase deficiency).

"A case of muscular dystrophy in a 1-year-old male castrated Domestic Shorthair cat is presented. The most striking clinical features were regurgitation, a stiff gait, an increased muscle tone and exercise intolerance. Serum biochemistry panels showed a marked increase in the muscle specific enzyme creatine kinase, and moderately elevated levels of LDH, AST and ALT. Spontaneous electrical activity of skeletal muscles in the form of \"bizarre high frequency discharges\" and \"myotonia-like repetitive discharges\" were registered. Gross pathology revealed a marked hypertrophy of the skeletal muscles. The main histopathological changes were myofiber necrosis and calcification, variation in fiber size, hypertrophied muscle fibers of type I and type II and fiber splitting. Indirect immunofluorescence showed dystrophin deficiency. Feline muscular dystrophy resembles the X-linked human Duchenne muscular dystrophy (DMD). Besides the X-linked muscular dystrophy in the mouse and Golden Retriever the feline muscular dystrophy could represent another valuable animal model for the study of DMD."

"In Duchenne muscular dystrophy, the progression of the disease is always severe and predictable, while in Becker dystrophy there is a wide variability (intra and inter familial) in the severity of the phenotype. We report here a family in which the proband, who is currently 15 years old, is showing a severe DMD progression, while his affected maternal uncle, aged 29, has a more benign course, compatible with BMD. No DNA deletion was detected in both patients. Dystrophin analysis through immunofluorescence and western blotting showed a negative pattern in the youngest patient and a positive one in the oldest.

duchenne:8235842 | Efficacy of spinal cord monitoring in neuromuscular scoliosis. | [
"Somatosensory cortical evoked potentials (SCEPs) monitoring in neuromuscular scoliosis surgery was evaluated in a large consecutive series of spinal reconstructions to define its role in the detection and prevention of spinal cord injury; 141 procedures in 101 patients were evaluated. In 28% a reliable tracing could not be obtained. Two postoperative neurologic deficits were missed by SCEP monitoring. Diagnosis (Duchenne muscular dystrophy and polio) was the only significant factor found to correlate with a reliable tracing. The use of sublaminar wires was associated with a higher rate of change in tracing. Transient changes were common. SCEPs are unreliable and nonspecific in neuromuscular scoliosis surgery and are not efficatious in preventing or detecting spinal cord injury when used alone.

duchenne:8186717 | Myoblast transplantation between monozygotic twin girl carriers of Duchenne muscular dystrophy. | [
"Monozygotic twin girls, both carriers of Duchenne muscular dystrophy, only one a severe symptomatic carrier and the other asymptomatic due to opposite lyonization, were studied. Myoblast clones were obtained from a muscle biopsy of the asymptomatic carrier. PCR amplification showed that most (94%) of these clones produced normal dystrophin mRNA. Roughly 704 million myoblasts were produced from 119 clones. These myoblasts were transplanted into the extensor carpi radialis (ECR) and in the biceps of one arm of the manifesting carrier while the other arm acted as the control. The strength of the patient was evaluated in a series of pre- and post-tests and a biopsy was obtained about 1 yr after the transplantation. The myoblast injections produced a significant force gain (12%-31%) in wrist extension but no force gain for elbow flexion. Muscle biopsies on the injected and control muscles obtained 1 yr after the injections showed only a small increase in the number of dystrophin positive fibers and the presence of numerous small type II fibers. The small beneficial effect of this transplantation cannot be attributed to immune problems, the donor and the recipient being identical twins, but may be due to a low level of spontaneous muscle regeneration."

duchenne:8186681 | Protein truncation test (PTT) to rapidly screen the DMD gene for translation terminating mutations. | [
"We have developed a rapid and sensitive method to screen the Duchenne muscular dystrophy (DMD) mRNA for translation terminating mutations by a combination of RT-PCR (Reverse Transcription and Polymerase Chain Reaction) and in vitro transcription/translation applied to white blood cell mRNA. This technique was termed the protein truncation test (PTT). Here we demonstrate the detection of a point mutation in a DMD patient and his mother, a carrier. The PTT can also be used for carrier detection when no patient material is available, or in the case of spontaneous mutations. We developed a protocol to screen the total coding region of the DMD gene in 5-10 PTT reactions. Furthermore, PTT could be of diagnostic value in any disease where premature terminations form a substantial part of the total mutation spectrum."

duchenne:8401582 | A missense mutation in the dystrophin gene in a Duchenne muscular dystrophy patient. | [
"About two thirds of Duchenne muscular dystrophy (DMD) patients have either gene deletions or duplications. The other DMD cases are most likely the result of point mutations that cannot be easily identified by current strategies. Utilizing a heteroduplex technique and direct sequencing of amplified products, we screened our nondeletion/duplication DMD population for point mutations. We now describe what we believe to be the first dystrophin missense mutation in a DMD patient. The mutation results in the substitution of an evolutionarily conserved leucine to arginine in the actin-binding domain. The patient makes a dystrophin protein which is properly localized and is present at a higher level than is observed in DMD patients. This suggests that an intact actin-binding domain is necessary for protein stability and essential for function."

duchenne:8349821 | Deficiency of dystrophin-associated proteins in Duchenne muscular dystrophy patients lacking COOH-terminal domains of dystrophin. | [
"Dystrophin, the protein product of the Duchenne muscular dystrophy (DMD) gene, is a cytoskeletal protein tightly associated with a large oligomeric complex of sarcolemmal glycoproteins including dystroglycan, which provides a linkage to the extracellular matrix component, laminin. In DMD, the absence of dystrophin leads to a drastic reduction in all of the dystrophin-associated proteins, causing the disruption of the linkage between the subsarcolemmal cytoskeleton and the extracellular matrix which, in turn, may render muscle cells susceptible to necrosis. The COOH-terminal domains (cysteine-rich and carboxyl-terminal) of dystrophin have been suggested to interact with the sarcolemmal glycoprotein complex. However, truncated dystrophin lacking these domains was reported to be localized to the sarcolemma in four DMD patients recently. Here we report that all of the dystrophin-associated proteins are drastically reduced in the sarcolemma of three DMD patients in whom dystrophin lacking the COOH-terminal domains was properly localized to the sarcolemma. Our results indicate that the COOH-terminal domains of dystrophin are required for the proper interaction of dystrophin with the dystrophin-associated proteins and also support our hypothesis that the loss of the dystrophin-associated proteins in the sarcolemma leads to severe muscular dystrophy even when truncated dystrophin is present in the subsarcolemmal cytoskeleton."

duchenne:8229051 | Immunohistological evidence for second or somatic mutations as the underlying cause of dystrophin expression by isolated fibres in Xp21 muscular dystrophy of Duchenne-type severity. | [
"Using five monoclonal antibodies against different parts of the dystrophin molecule, we have studied the dystrophin composition of 17 dystrophin-positive fibres in a muscle biopsy from a boy with Xp21 muscular dystrophy of Duchenne-type severity. The fibres showed five distinct, reproducible, immunoreactive dystrophin profiles. All the profiles included both the N-terminal and the C-terminal domains, but between these domains, different fibres were negative for different antibodies, suggesting the somatic loss of certain exons. We interpret this as the first in situ evidence of an individual having different patterns of missing exons leading to restoration of the reading frame in various ways in the original germline frame-shifting deletion of exons 35-43. It follows that various somatic mutations had taken place in different fibres."

"A 10-year-old boy with Duchenne muscular dystrophy (DMD), with quite unusual clinical data, is presented. He was unable to walk until age 6, walked only for 9 months and then became wheel-chair bound. No dystrophin was present on muscle biopsy sections and a large deletion was found in the dystrophin gene. The deletion encompassed the central high frequency deletion region of the gene. Early developmental milestones may be delayed in DMD, but patients usually start to walk around 2-3 years of age. A delay of the extent in this case is very unusual."

duchenne:8357005 | Mental retardation locus in Xp21 chromosome microdeletion. | [
"Xp21 microdeletion syndrome is associated with variable size Xp21 deletions that usually include the glycerol kinase locus. The clinical phenotypes we studied in this chromosome region include: Xpter - Aland Island eye disease (AIED) -adrenal hypoplasia (AH) -glycerol kinase (GKD) -Duchenne muscular dystrophy (DMD) -retinitis pigmentosa (RP) -ornithine transcarbamylase (OTC) -centromere. In a compilation of 18 individuals in 14 families with the AH, GKD, and DMD loci deleted, 17 were male and all were developmentally delayed. In contrast, we report mentally retarded female carriers in two Xp21 deletion syndrome families with DMD, GKD, and AH in affected males. In the first family with normal karyotypes, a submicroscopic deletion was associated with DMD in the retarded male and with retardation in carrier females. In the second family an X chromosome with a cytogenetically deleted Xp21 distal to the OTC and RP genes segregated in the affected male and retarded female carriers. DNA analysis at the DMD locus verified the cytogenetic findings. This report of mental retardation in otherwise asymptomatic female carriers of Xp21 deletion classifies one form of mental retardation in females."

"DNA methods to diagnose Duchenne muscular dystrophy (DMD) are not always informative, and we have published previously the first instance of in utero muscle biopsy to assess dystrophin in a male fetus having the same \"X\" as an affected sib. We present here a female fetus with a de novo X,1 translocation with breakpoint at Xp21, detected on amniocentesis for advanced maternal age. The translocation breakpoint placed her at high risk for DMD. In utero muscle biopsy at 20 weeks of gestation produced a specimen positive for dystrophin immunofluorescence indicating a likely normal fetus. The pregnancy was continued, and at term the baby girl was found to have normal serum creatine kinase levels, and was therefore unaffected with DMD. Our experiences add de novo Xp21 translocation to the indications for in utero muscle biopsy for diagnosis of DMD."

duchenne:8387534 | Insertion of a 5' truncated L1 element into the 3' end of exon 44 of the dystrophin gene resulted in skipping of the exon during splicing in a case of Duchenne muscular dystrophy. | [
"We report here the second evidence of retrotransposition of L1, which was found inserted into the dystrophin gene of a patient, causing Duchenne muscular dystrophy (DMD). When the PCR was used to amplify a region of the dystrophin gene encompassing exon 44 from genomic DNA of two Japanese brothers with DMD, it was found to be approximately 600 bp larger than expected. Both the normal and the abnormally large products were amplified from the DNA of their mother. However, the maternal grandparents did not have the abnormal allele, and the mutation must therefore have occurred in the mother. Analysis of nucleotide sequence of the amplified product from a patient disclosed that the insertion was present zero to two bases upstream from the 3' end of exon 44 and that two to four bases of the exon sequence were deleted from the insertion site. The insertion sequence was found to be composed of 606-608 bp and to be almost identical to the inverse complement of 3' portion of the L1 retrotransposon consensus sequence. The dystrophin gene transcript from peripheral lymphocytes of one of the patients was analyzed by using reverse transcription/semi-nested PCR. The size of the amplified product encompassing exon 42 to 46 was smaller than expected. Sequencing of the amplified product disclosed that the sequence of exon 43 was directly joined to that of exon 45. Exon 44 of the transcript was thus shown to be skipped during splicing. This novel mutation of the dystrophin gene has important implications regarding retrotransposition of an active L1 element and provides a new insight into the origins of mutations in the dystrophin gene."

duchenne:8375105 | Germinal mosaicism in a Duchenne muscular dystrophy family: implications for genetic counselling. | [
"In this study we describe a three-generation family in which two siblings were affected by Duchenne muscular dystrophy (DMD). Immunohistochemical analysis of muscle dystrophin and haplotype analysis of the DMD locus revealed that the X chromosome carrying the DMD gene was transmitted from the healthy maternal grandfather to his three daughters, including the proband's mother. These findings indicate that the grandfather was a germinal mosaic for the DMD gene. The definition of the carrier status in two possible carriers led us to give accurate genetic counselling and to prevent the birth of an affected boy. The results of this study demonstrate the usefulness of haplotype analysis and immunohistochemical muscle dystrophin studies to detect hidden germinal mosaicism and to improve genetic counselling."

"Details of disease progression and dystrophin expression are presented for three patients with Duchenne muscular dystrophy (DMD) who unexpectedly had intragenic deletions which maintained the open reading frame for mRNA translation. Analysis of dystrophin in muscle biopsies showed variable dystrophin synthesis in all three patients. Two with relatively small deletions (missing exons 10-13 and 52-55) had low levels of dystrophin which were comparable to those found in many DMD patients. The third patient (with a larger deletion which removed exons 3-25) produced dystrophin in the high abundance which is normally associated with patients who have Becker muscular dystrophy. This is the first time that a patient has been described with the clinical phenotype of DMD, a large amount of dystrophin which was correctly localized at the periphery of muscle fibres and an in-frame deletion of exons in the amino terminal domain."

"We report a family with manifesting DMD carriers over two generations. Sixty years old female (case 1) suffered from slowly progressive weakness since her thirties. Her youngest daughter aged 30 (case 2) had cramping calf muscle pain since her 5 years old. Progressive muscle weakness developed and lost her ambulation by the age of 20. Grandson of case 1 (son of case 1's eldest daughter who has no clinical symptoms) was diagnosed as DMD with deletion of exon 19-21 in dystrophin gene. Case 1 and case 2 were revealed to be DMD carriers. We speculate that, in this family, X-inactivation process was not random and paternal X was preferentially inactivated by maternal mutant X."

duchenne:8481629 | Heterozygotic gene expression in endomyocardial biopsies: a new diagnostic tool confirms the Duchenne carrier status. | [
"Identification of the defective gene and the absent gene product dystrophin can substantiate the clinical evidence for manifesting X-linked Duchenne type muscular dystrophy (DMD). It is not always possible, however, to rule out definitely a clinically asymptomatic carrier status in question, since even in the proven carrier DNA analysis is often inconclusive, and multinucleated skeletal muscle fibers express a basically normal membrane dystrophin. To substantiate the value of endomyocardial biopsy as a new tool for detection of the DMD carrier status we examined an endomyocardial biopsy of a volunteer who met the clinical criteria of a DMD carrier. Dystrophin immunohistochemistry and western blot of her skeletal muscle biopsy were inconclusive, and polymerase chain reaction and cDNA analysis failed to locate directly the X-chromosomal defect. We observed a clearcut mosaic of dystrophin-positive and -negative mononucleated cardiac muscle cells, reflecting a heterozygote carrier status in her endomyocardial biopsy, whereas 20 controls were uniformely positive.

duchenne:8456832 | In situ hybridization shows direct evidence of skewed X inactivation in one of monozygotic twin females manifesting Duchenne muscular dystrophy. | [
"A novel combination of conventional and molecular cytogenetic techniques was used to investigate the expression of an X-linked recessive disorder in one of monozygotic (MZ) twin females. These twins carry a deletion, approximately 300 kb in length, in one of their X chromosomes within the dystrophin gene, which is responsible for Duchenne muscular dystrophy (DMD) in one twin [Richards et al.: Am J Hum Genet 46:672-681, 1990]. A unique DNA fragment generated from an exon within this gene deletion was hybridized in situ to both twins' metaphase chromosomes, a probe which would presumably hybridize only to the normal X chromosome and not to the X chromosome carrying the gene deletion. Chromosomes were identified by reverse-banding (R-banding) and by the addition of 5-bromodeoxyuridine (BrdU) in culture to distinguish early and late replicating X chromosomes, corresponding to active and inactive X chromosomes, respectively. Hybridization experiments showed predominant inactivation of the normal X chromosome in the twin with DMD. This is the first report showing direct evidence at the chromosome level of unequal inactivation of cytogenetically normal X chromosomes resulting in the manifestation of an X-linked recessive disorder in one of monozygotic twin females. This study may now facilitate other research of unequal X inactivation and of females manifesting X-linked recessive disorders."

duchenne:8358237 | Dystrophin-positive myotubes in innervated muscle cultures from Duchenne and Becker muscular dystrophy patients. | [
"Nerve-muscle co-cultures from five Duchenne muscular dystrophy (DMD) patients and one Becker (BMD) patient, were studied by immunocytochemistry with antibodies against different portions of dystrophin. Four DMD patients had a deletion in the dystrophin gene. Some dystrophin-positive myotubes were detected in a few samples of all DMD cases. PCR amplification of exon 8 of the dystrophin gene ruled out a contamination from rat spinal cord during innervation. Our results in three DMD cases, may be explained by a clonal selection of dystrophin-positive fibers observed in muscle biopsies, while in the other two cases, a \"frame-restoring\" mutation might account for the presence of dystrophin-positive myotubes. The possible expression of \"dystrophin-related protein\" or dystrophin immature isoform was considered. In the BMD case an abnormal truncated dystrophin was found in innervated muscle cultures, as well as in muscle biopsy."

duchenne:8490621 | Is the maintainance of the C-terminus domain of dystrophin enough to ensure a milder Becker muscular dystrophy phenotype? | [
"The severe Duchenne muscular dystrophy (DMD) and the more benign Becker type (BMD) are allelic conditions, controlled by a defective gene at Xp21, caused by the absence (DMD) or a defect in quantity or quality (BMD) of the protein dystrophin. It has been suggested that the C-terminus domain of dystrophin is fundamental to ensure the proper protein sub-cellular localization and function. We wish to report our dystrophin findings in 4 among 142 DMD patients studied for DNA deletions and dystrophin analysis. Although they have a severe clinical course, a positive dystrophin immunofluorescence pattern was seen using C-terminal antibody, and a dystrophin band of reduced molecular weight (corresponding to their DNA deletions), but which maintained the C-terminus was seen through Western blot (WB). Based on these findings, we suggest that in order to partially maintain its function, resulting in a milder phenotype, dystrophin may carry large internal deletions but in addition to the C-terminus, the region encompassing both the N-terminus and the proximal region of the rod domain cannot be absent. Therefore, the prognosis of a Becker phenotype in a young patient should be done with caution if based only on the presence or not of dystrophin."

"The dystrophinopathies are muscle disorders due to an abnormality of an Xp21-linked gene which produces the dystrophin protein. The most common of these disorders are the Duchenne and Becker muscular dystrophies. Modern molecular genetic techniques enable reliable diagnosis and prognosis in many patients, but there are occasional pitfalls. Furthermore, the clinical spectrum of the dystrophinopathies are now such that the clinician needs to be aware of a broader range of clinical disorders that require analysis of the dystrophin gene and its product, not just those that mirror a classic Duchenne or Becker muscular dystrophy picture. This spectrum ranges from a severe form presenting at birth to asymptomatic elevation of CK. Females may be manifesting carriers or present as a severe phenotype when the abnormal gene is expressed as an X-autosome translocation or monosomy X. Laboratory diagnosis and prognosis can be made most accurately by using both DNA analysis at the dystrophin gene and immuno-analysis of muscle with antibodies directed against different regions of the protein product. This review describes some exemplary patients, suggests a clinical classification for dystrophinopathies, and outlines a diagnostic approach."

"Monoclonal antibodies recognizing different epitopes of dystrophin have now been widely applied in diagnostic tests for Duchenne and Becker muscular dystrophy (BMD). The preservation of the C-terminus in BMD patients necessitates the routine use of one antibody raised against this region.

duchenne:8364587 | Exon 44 nonsense mutation in two-Duchenne muscular dystrophy brothers detected by heteroduplex analysis. | [
"Utilizing a heteroduplex method, we screened the dystrophin exon 43-45 region for point mutations, including small deletions and insertions. The method depends upon the formation of a heteroduplex between wild-type and mutant DNA PCR products. DNA specimens from one hundred and four DMD patients without detected deletions or duplications were multiplexed amplified for exons 43, 44, and 45. The PCR products were mixed with the PCR products from nonaffected controls, electrophoresed, and examined for the presence of altered mobility heteroduplex bands. An exon 44 nonsense mutation in two DMD brothers and a common intron 44 polymorphism were identified using this approach. Although the exon 44-45 region is a hotspot for deletion breakpoints, it does not appear to be prone to point mutations. The technique is extremely useful for screening several exons simultaneously and it allowed us to screen a large number of patients."

duchenne:8329890 | Variability in clinical, genetic and protein abnormalities in manifesting carriers of Duchenne and Becker muscular dystrophy. | [
"We have analysed the results of clinical assessment, X-inactivation status, deletion screening and dystrophin analysis in eight manifesting carriers of Duchenne and Becker muscular dystrophy (DMD and BMD). Only two had a prior family history of X-linked muscle disease, all had normal karyotypes and none were twins. Presentation varied from 2 to 25 yr and progression varied from a DMD-like severity to a very mild BMD-like course. In one girl the initial symptoms were restricted to learning difficulties. Where methods for assessing X-inactivation were informative, three patients showed an abnormal pattern. However, in one patient, the obligate carrier daughter of a BMD patient who had presented at the age of 2 yr, X-inactivation appeared normal in lymphocytes and muscle. While dystrophin analysis seems to be reliable in identifying manifesting carriers of DMD and BMD, the relationship between X-inactivation status, dystrophin analysis and phenotype is not simple."

duchenne:8095479 | Diagnosis of DMD carrier status in a family with no known affected males. | [
"A 30-year-old woman and her two-year-old daughter were found by chance to have moderately raised serum creatine kinase (CK) levels. Since the mother was pregnant, the authors investigated the possibility that the two females were carriers of the common Duchenne muscular dystrophy (DMD) gene. No immunohistochemical abnormality was detected in the mother, but in the daughter a clear mosaic pattern of dystrophin positive and negative fibres was found, indicating carrier status for DMD. These data indicate that a diagnosis of DMD carrier status can be made even in families without a positive history for this disorder; therefore, immunocytochemical studies, using antidystrophin antibodies, should be performed on all females with raised CK levels, including the youngest."

"We report the occurrence of Hunter disease (mucopolysaccharidosis type II) in a karyotypically normal girl who was one of identical twins. Molecular studies showed nonrandom X-inactivation in both her fibroblasts and lymphocytes, while her normal twin showed equal usage of both X chromosomes. In view of previous reports of 7 pairs of identical female twins in which one had Duchenne muscular dystrophy, it seems that twinning may be strongly associated with nonrandom X-inactivation, and is not specific to the properties of the disease causing gene."

"Allele-specific molecular diagnosis of Duchenne and Becker muscular dystrophies (DMD and BMD) has been largely dependent upon muscle biopsy for dystrophin protein assay. We performed lymphocyte DNA mutation analysis by polymerase chain reaction on 14 boys presenting with a clinical picture compatible with DMD or BMD. DNA analysis revealed that 12 of 14 boys had a deletion of the dystrophin gene, thus establishing the diagnosis of DMD/BMD. Furthermore, genotypes for 9 of 12 deletion patients permitted prediction of the specific allelic disorder (i.e., DMD or BMD). Subsequent dystrophin testing confirmed all of the DNA-based diagnoses. We propose that DNA mutation analysis be included in the initial evaluation of patients suspected of having DMD/BMD, thus potentially eliminating the need for muscle biopsy in the majority of patients."

duchenne:1513469 | Premature chain termination mutation causing Duchenne muscular dystrophy. | [
"We identified a premature chain termination mutation in two brothers with Duchenne muscular dystrophy and correlated the mutation in one of the brothers with immunologic detection of dystrophin in skeletal muscle. Southern and polymerase chain reaction (PCR) studies of genomic DNA from the affected boys showed no major gene rearrangements. However, the noted absence of a HindIII Southern fragment containing the proximal portion of exon 48 led to the identification of a point mutation that creates a new HindIII restriction site in that exon. Exon 48 was amplified by PCR from DNA of the patients and other family members and digested with HindIII to show the mutation in the two boys and also in their mother and maternal grandmother. Direct DNA sequencing demonstrated a cytosine-to-thymine transition at nucleotide 7163 of dystrophin that converts a glutamine codon (CAA) to an ochre chain termination codon (UAA). This mutation predicts a truncated dystrophin missing the distal spectrin-like repeat region, the cysteine-rich domain, and the carboxy terminal. Immunohistochemistry of skeletal muscle from one of the affected boys revealed membrane-localized dystrophin in the majority of fibers detected by anti-dystrophin antibodies against (1) the amino terminal and (2) part of the spectrin-like repeat region; both regions would be present in the truncated dystrophin predicted by the chain termination mutation. This suggests that the carboxy terminal may not be an absolute requirement for dystrophin membrane localization. Very few muscle fibers also showed peripheral immunostaining using anti-dystrophin antibodies against the carboxy terminal, suggesting gene reversion, suppression, or read-through in these rare fibers."

duchenne:1472706 | A case of atypical Duchenne type muscular dystrophy with fragile X. | [
"The patient was a 9-year-old boy. He began to walk at the age 1 year and 8 months and began to speak at the age of 2 years, suggesting retarded mental and motor development. A diagnosis of DMD was made when he was 7 years old. On admission, the patient exhibited a peculiar thin and long face, large auricles, narrow palate, malalignment of the teeth, epicanthus, saddle nose, and simian lines in addition to symptoms consistent with DMD. Chromosome analysis showed fragile X at Xq27 at a frequency of 20%. His mother also showed fragile X at the same position. Since the atypical features of this DMD patient are all explained as fragile X syndrome, this case was considered to be a very rare instance of DMD whose clinical pictures were modified by fragile X syndrome."

duchenne:1427785 | Prenatal diagnosis of Duchenne muscular dystrophy by fetal muscle biopsy. | [
"Prenatal diagnosis and carrier detection for Duchenne muscular dystrophy (DMD) usually can be performed using DNA analysis. When recombination occurs within the DMD gene, or DNA analysis is uninformative, or in pedigrees where it is unclear whether or not the consultand is a carrier, direct examination of muscle by dystrophin analysis may provide the only means of prenatal diagnosis. We present three cases representing each of these molecular genetic diagnostic dilemmas. In each instance, we used sonographically guided fetal muscle biopsy for dystrophin protein analysis to resolve the dilemma. In the first and third cases, the presence of normal dystrophin was shown by immunofluorescence and this was followed by delivery of an unaffected male fetus. In the second case, dystrophin was not found in fetal muscle tissue implying that this fetus was affected. The absence of dystrophin and affected status was confirmed in skeletal and cardiac muscle obtained after pregnancy termination."

"The detailed genetic analysis of the Duchenne/Becker muscular dystrophy gene is hindered by the large number of exons involved and their separation by huge introns. These problems can be overcome by the analysis of mRNA rather than genomic DNA and ectopic transcripts derived from peripheral blood lymphocytes provide a convenient source of material. Using reverse transcription and nested PCR, we show here a comprehensive strategy for the rapid and complete analysis of the coding sequences from complex genes and illustrate its potential by the identification of a hitherto undescribed single exon deletion."

duchenne:1644931 | An intact cysteine-rich domain is required for dystrophin function. | [
"The carboxyl terminus of dystrophin is encoded by a highly conserved, alternatively spliced region of the gene. The few rare mutations reported in this region are of interest in unraveling the function of the dystrophin molecule. An unusual case of infantile onset Duchenne muscular dystrophy (DMD) with an internal 3' genomic deletion, and a membrane localized non-functional dystrophin protein, was used to explore the functional activity of this region. The patient's cDNA sequence showed an intragenic 1824-bp deletion precisely excising the cysteine rich and alternatively spliced COOH-terminal domains of dystrophin. The unaltered final 2.7 kb of the patients transcript was defined as a single exon localized to two genomic fragments, with the 5.9 kb HindIII fragment containing the stop codon. To understand the significance of deletions in this important region of the dystrophin gene, we mapped the order and cDNA coordinates for the 3' genomic HindIII fragments encoding the cysteine rich and alternative splicing domains. This 3' gene map was used to compare the clinical phenotype of the other reported COOH-terminal deletions in the literature. Our analysis concludes that the cysteine-rich domain confers an important function for the dystrophin protein."

duchenne:1518025 | Investigation of a female manifesting Becker muscular dystrophy. | [
"Females manifesting Becker muscular dystrophy (BMD) are even more rarely observed than for the allelic condition Duchenne muscular dystrophy. The male proband has typical BMD with greatly raised CK activity and a myopathic muscle biopsy. His mother experienced walking difficulties from 35 years of age and has a myopathy with marked calf hypertrophy, a raised CK, and a myopathic muscle biopsy. Dystrophin analysis was undertaken on both the proband and his mother. Immunoblotting showed a protein of normal size but of reduced abundance in both. Immunocytochemical analysis in the proband indicated that the majority of the fibres showed weak dystrophin labelling and in his mother both dystrophin positive and dystrophin negative fibres were present. Non-random X inactivation at locus DXS255, was observed in DNA isolated from peripheral lymphocytes of the mother. Neither extended multiplex PCR performed on DNA from the proband nor analysis of lymphocyte derived mRNA showed a structural alteration in the dystrophin gene suggesting that an unusual mutation was responsible for BMD in this family."

"Three cases of muscular dystrophy are reported on (8 years, 4 months, 10 months) in which serious conditions arose under anaesthetic (bradycardia, asystolia, hyperkalemia, rising CPK). In the first two cases there was no way of avoiding a fatal outcome, but in the third case the child survived with no permanent damage. The cause of incidents of this kind is discussed first as being hyperkalemia due to acute rhabdomyolysis, and secondly malign hyperthermia. There were no indications of malign hyperthermia in this case. It is hardly possible to distinguish this in an acute clinical ward, as the clinical symptoms are very similar. If it is known that muscular dystrophy is present, depolarising relaxants should be given sparingly. This also applies, as the first case shows, for muscular dystrophy of the Becker type, which can on the whole be regarded as benign in comparison with progressive muscular dystrophy of the Duchenne type. In this instance a forensic and anaesthetic expert's opinion even had to be produced at the request of the Public Prosecutor. The post mortem was carried out under the heading of a possible \"mistaken medical treatment\" but there was no evidence to justify such an assumption."

duchenne:1415326 | X inactivation and dystrophin studies in a t(X;12) female: evidence for biochemical normalization in Duchenne muscular dystrophy carriers. | [
"A 4-year-old girl was identified with high creatine kinase (CK) values, and mild muscle weakness in a limb-girdle distribution. Results of dystrophin analysis of the muscle biopsy were consistent with a manifesting heterozygote for Duchenne muscular dystrophy. In peripheral lymphocytes she had a t(X;12) (p21.2;q24.33). Late DNA replication studies demonstrated inactivation of the normal X chromosome in 99.4% of cells. Dystrophin immunofluorescence showed 64% dystrophin-negative muscle fibers. Dystrophin content of muscle by immunoblot was approximately 5% of normal. The discordance between the percent of normal X inactivation and percent of dystrophin-negative cells may be explained by compensatory protection of dystrophin by rare nuclei with the normal X active in multi-nucleated muscle fibers with shared cytoplasm."

"Carrier testing in a Duchenne muscular dystrophy (DMD) family resulted in the identification of a case of germline mosaicism. Using dystrophin cDNA probes, this phenomenon was ascertained by the demonstration of a deletion junction fragment present in the DNA of the affected patient and one sister but absent in the mother's DNA. As a result of this finding carrier risk estimations, based on restriction fragment length polymorphism (RFLP) studies, were significantly altered.

duchenne:1615933 | Optimization of DNA extraction from formalin-fixed tissue and its clinical application in Duchenne muscular dystrophy. | [
"The authors report a case of Duchenne muscular dystrophy in which a deletion was determined by multiplex polymerase chain reaction using postmortem tissue from a proband who died in 1985, 2 years before the cloning of the dystrophin gene. Several extraction methods were analyzed to determine optimal conditions for recovery of DNA from fixed tissue. Variables examined were tissue lysis times and temperatures, a simple salting-out procedure for purification of DNA, polymerase chain reaction amplification of crude lysate versus purified DNA, and lysis of different tissues and tissue quantities. Extracted DNA was analyzed spectrophotometrically, electrophoretically, and by its suitability for polymerase chain reaction amplification using exon flanking primers of the dystrophin gene. Lysis at 37 degrees C for less than 24 hours led to the recovery of predominantly low-molecular-weight DNA, which was unsuitable for polymerase chain reaction in this experience. Lysis at 54 degrees C consistently yielded visible, spoolable quantities of high-molecular-weight DNA in as little as 24 hours. Direct amplification of crude, unpurified lysates was unsuccessful. However, purified samples yielded consistent amplification products. The purification step was simplified by substituting a rapid salting-out procedure for organic extractions."

duchenne:1388424 | Phenotypic Duchenne muscular dystrophy with C-terminal domain. | [
"We report a patient with X-linked muscular dystrophy who had rapidly progressive muscle weakness and became wheelchair-bound at age 10 years. Clinically, he was diagnosed as having Duchenne muscular dystrophy; however, he was diagnosed as having Becker muscular dystrophy by dystrophin tests using a C-terminal monoclonal antibody. No immunolabelling was observed with a monoclonal antibody against the N-terminal domain. Multiplex polymerase chain reaction analysis revealed the deletion of exons 3-19. The data suggest that the deletion of the N-terminal domain of dystrophin can cause a severe phenotype even when the C-terminus of the protein is well preserved."

"The presence of myocardial involvement is rare in benign Duchenne type of progressive muscular dystrophy (Becker's muscular dystrophy). We describe two brothers suffering from Becker's muscular dystrophy, both of whom presented with dilated cardiomyopathy. The first case is a 39-year-old male who had suffered from gait disturbance from the age of 17. When 37 years old, he was found to have heart disease. When he first came to our hospital, pseudohypertrophy of the calves was present. Chest radiography, electrocardiogram, ultrasonocardiography and clinical feature indicated Becker's muscular dystrophy with dilated cardiomyopathy. The second case is the younger brother of the 37-year old male. He suffered from leg weakness. He came to our hospital with the chief complaint of discomfort of the anterior chest. Pseudohypertrophy of the calves was present. Chest radiography, electrocardiogram, ultrasonogram indicated dilated cardiomyopathy."

duchenne:1347968 | Common sequence motifs at the rearrangement sites of a constitutional X/autosome translocation and associated deletion. | [
"Reciprocal chromosome translocations are common de novo rearrangements that occur randomly throughout the human genome. To learn about causative mechanisms, we have cloned and sequenced the breakpoints of a cytologically balanced constitutional reciprocal translocation, t(X;4)(p21.2;q31.22), present in a girl with Duchenne muscular dystrophy (DMD). Physical mapping of the derivative chromosomes, after their separation in somatic cell hybrids, reveals that the translocation disrupts the DMD gene in Xp21 within the 18-kb intron 16. Restriction mapping and sequencing of clones that span both translocation breakpoints as well as the corresponding normal regions indicate the loss of approximately 5 kb in the formation of the derivative X chromosome, with 4-6 bp deleted from chromosome 4. RFLP and Southern analyses indicate that the de novo translocation is a paternal origin and that the father's X chromosome contains the DNA that is deleted in the derivative X. Most likely, deletion and translation arose simultaneously from a complex rearrangement event that involves three chromosomal breakpoints. Short regions of sequence homology were present at the three sites. A 5-bp sequence, GGAAT, found exactly at the translocation breakpoints on both normal chromosomes X and 4, has been preserved only on the der(4) chromosome. It is likely that the X-derived sequence GGAATCA has been lost in the formation of the der(X) chromosome, as it matches an inverted GAATCA sequence present on the opposite strand exactly at the other end of the deleted 5-kb fragment. These findings suggest a possible mechanism which may have juxtaposed the three sites and mediated sequence-specific breakage and recombination between nonhomologous chromosomes in male meiosis."

duchenne:1549596 | Point mutations in the dystrophin gene. | [
"Defining the range of mutations in genes that cause human disease is essential to determine the mechanisms of genetic variation and the function of gene domains and to perform precise carrier and prenatal diagnosis. The mutations in one-third of Duchenne muscular dystrophy patients remain unknown as they do not involve gross rearrangements of the dystrophin gene. The size and complexity of the gene have prohibited the systematic definition of point mutations. We have developed a method for the identification of these mutations by nested amplification, chemical mismatch detection, and sequencing of reverse transcripts of trace amounts of dystrophin mRNA from peripheral blood lymphocytes. Analysis of the entire coding region (11 kilobases) in seven patients has resulted in detection of a sequence change in each case that is clearly sufficient to cause the disease. All mutations should cause premature translational termination, and the resulting phenotypes are thus equivalent to those caused by frameshifting deletions. The results support a particular functional importance for the C-terminal region of dystrophin. Application of this approach to mutation detection will extend direct carrier and prenatal diagnosis to virtually every affected family."

"Intramuscular degeneration process of Duchenne dystrophy skeletal muscles was investigated by longitudinal skeletal muscle imaging with high-field-strength NMR-CT of 1.5 Tesla. Thigh muscles in 10 cases ranging in age from 4 to 19 years were examined by T1-weighed longitudinal images (TR = 215-505 ms, TE = 19-20 ms). Following results were obtained: (1) Skeletal muscle degeneration was depicted as high signal intensity area reflecting its high fat contents. (2) These high signal intensity areas had a longitudinally streaky appearance in parallel direction with myofibers. (3) These findings were more prominent toward myotendon junction than muscle bellies. (4) Skeletal muscle degeneration progressed rapidly between 7 to 10 years of age, and reached a plateau after that."

duchenne:1539591 | A truncated dystrophin lacking the C-terminal domains is localized at the muscle membrane. | [
"A Duchenne muscular dystrophy patient who displayed near-normal dystrophin staining at the sarcolemma with N-terminal, but not with C-terminal, anti-dystrophin monoclonal antibodies was found to have a frameshift deletion of exons 42 and 43. This deletion introduces an early termination codon, and a 225-kD protein was detected by western blotting with N-terminal antibodies only. The results suggest that an N-terminal truncated dystrophin fragment encoded by exon 1-41 is able to associate with the muscle cell membrane. The current idea that the C-terminal domains of dystrophin are important or essential for its integration with the sarcolemma may have to be reexamined in the light of these observations."

"Muscles from Becker muscular dystrophy (BMD) and Duchenne muscular dystrophy (DMD) patients were analysed using monoclonal and polyclonal antibodies raised against different regions of the dystrophin molecule. On blot, two of the antibodies detected a protein of Mr 400K in muscle extracts from all patients, including a BMD patient with a deletion which spanned more than 40% of the central rod domain of the Xp21 encoded dystrophin. Immunocytochemical labelling of tissue sections from the same patients showed that the same two antibodies labelled a protein at the surface membrane of smooth muscle fibers in blood vessels of both BMD and DMD muscles. Thus we have demonstrated a 400K blood vessel-associated protein, which is immunologically homologous with dystrophin, for at least two epitopes from the carboxy terminal and the central rod domains must be encoded by another gene than the dystrophin gene."

"The rapid progress of research on the structure of the dystrophin gene has enormously increased our understanding of the molecular basis of Duchenne (DMD) and Becker (BMD) muscular dystrophy. Apart from \"classical\" clinical presentations, asymptomatic or only mildly affected individuals with deletions in the dystrophin gene have now been reported. We describe two families which were initially classified as metabolic myopathies, until the diagnosis of atypical BMD was established after dystrophin analysis at the protein and DNA level.

duchenne:1537352 | Somatic mosaicism for a deletion of the dystrophin gene in a carrier of Becker muscular dystrophy. | [
"Duchenne muscular dystrophy (DMD) and the allelic milder form of Becker muscular dystrophy (BMD) are caused by mutations of the dystrophin gene on the short arm of the X chromosome. One third of affected individuals are expected to result from de novo mutations. Genetic counselling of families with sporadic cases is complicated by the potential meiotic origin of the mutation in the mother resulting in germline mosaicism. Here we present direct evidence for combined somatic and germline mosaicism for a deletion of the dystrophin gene, thereby proving the mitotic origin of this deletion and pinpointing a further potential pitfall for genetic counselling. The mother of a BMD son and a BMD carrier daughter, both carrying a deletion of dystrophin cDNA 7 (0.5 kb Hind III fragment) and cDNA 8, was herself clinically healthy and had normal creatine kinase levels. A muscle specimen of the mother showed mild overall pathology as well as focal dystrophin deficiency. In contrast chromosomal in situ suppression (CISS) hybridization of metaphase chromosomes using a cosmid clone of the corresponding cDNA deleted in her son revealed no evidence of somatic mosaicism in their lymphocytes. These results emphasize the value of an approach correlating genetic and immunological data for the definition of a carrier state in BMD or DMD. The possibility of somatic mosaicism should be considered when genetic counselling of a family with a sporadic case of BMD or DMD is performed."

duchenne:1731332 | Possible influences on the expression of X chromosome-linked dystrophin abnormalities by heterozygosity for autosomal recessive Fukuyama congenital muscular dystrophy. | [
"Abnormalities of dystrophin, a cytoskeletal protein of muscle and nerve, are generally considered specific for Duchenne and Becker muscular dystrophy. However, several patients have recently been identified with dystrophin deficiency who, before dystrophin testing, were considered to have Fukuyama congenital muscular dystrophy (FCMD) on the basis of clinical findings. Epidemiologic data suggest that only 1/3500 males with autosomal recessive FCMD should have abnormal dystrophin. To explain the observation of 3/23 FCMD males with abnormal dystrophin, we propose that dystrophin and the FCMD gene product interact and that the earlier onset and greater severity of these patients' phenotype (relative to Duchenne muscular dystrophy) are due to their being heterozygous for the FCMD mutation in addition to being hemizygous for Duchenne muscular dystrophy, a genotype that is predicted to occur in 1/175,000 Japanese males. This model may help explain the genetic basis for some of the clinical and pathological variability seen among patients with FCMD, and it has potential implications for understanding the inheritance of other autosomal recessive disorders in general.

"Malignant hyperthermia (MH) is a rare clinical syndrome characterized by hypermetabolism and triggered by specific anesthetic agents. The mechanism of this abnormal reaction is due to uncontrolled calcium flux in the skeletal muscles resulting in a variable clinical syndrome of muscle rigidity, respiratory and metabolic acidosis, and elevation of temperature. The specific genetic defect underlying this condition has not been identified in humans, though in susceptible swine a mutation of the gene for the ryanodine receptor, a large protein which comprises the calcium channel in the sarcoplasmic reticulum, has been identified recently. Inheritance in humans appears to be autosomal dominant with variable penetrance. Patients with MH rarely have physical or laboratory signs of muscle disease. However, scattered case reports and investigations of individuals with known myopathies and other muscle related problems, such as acute rhabdomyolysis or idiopathic persistently elevated creatine kinase, suggest a possible association of MH with a variety of neuromuscular diseases and stress syndromes. This association is very strong in the case of central core disease (CCD) where it is supported by clinical and laboratory evidence, including the proximity of the CCD gene to the ryanodine receptor gene on chromosome 19. A variety of other diseases have been implicated and can be classified as possibly associated (King-Denborough syndrome, Duchenne muscular dystrophy) or unlikely to be associated (myotonia congenita, sudden infant death syndrome, limb girdle dystrophy, neuroleptic malignant syndrome, etc.).(ABSTRACT TRUNCATED AT 250 WORDS)"

duchenne:1422198 | A deletion including the brain promoter of the Duchenne muscular dystrophy gene is not associated with mental retardation. | [
"A total of 161 unrelated Duchenne (DMD) and Becker muscular dystrophy (BMD) patients were screened for deletions in the brain promoter region of the dystrophin gene. Southern blot analysis using a probe for the brain promoter detected a deletion in this region in only one of the DMD families, in a patient with normal intelligence. This deletion also included the promoter of the muscle-type dystrophin and the exons encoding the actin-binding and part of the spectrin-like domains. Our data suggest that deletions in the brain promoter region are rare in DMD and are compatible with normal intelligence."

duchenne:1370218 | A symptomatic female patient with Duchenne muscular dystrophy diagnosed by dystrophin-staining: a case report. | [
"We report a case of symptomatic carrier of Duchenne muscular dystrophy (DMD) in a 14-year-old girl with no prior family history of DMD. She presented with chest pain, enlarged calf muscles, an elevated serum creatine kinase (CK), and decreased left ventricular function. Histological examination of skeletal muscle revealed myopathic changes and immunostaining with anti-dystrophin antiserum demonstrated a mosaic pattern which are compatible with the observations in carriers of DMD. Southern blots using the dystrophin cDNA revealed no evidence of a deletion within the DMD gene in the patient or in her mother. We found this observation interesting for two reasons: 1. Cardiomyopathy is rare in female DMD patients. 2. Immunostaining of a muscle biopsy with anti-dystrophin serum proved to be valuable in the diagnosed for symptomatic carriers of the dystrophin gene mutation."

The study of the results obviously showed the interest of Luque Galveston technique for the treatment of severe curves with pelvic obliquity, whereas Dove's rectangle is an interesting choice for the early instrumentation.

"A 30-year-old man showed exercise-induced myalgia, calf muscle hypertrophy and high serum creatine kinase level, without muscular weakness. The symptoms began in childhood and did not progress. Electromyographic findings were consistent with myopathy, and the muscle histology showed nonspecific myopathic changes without evidence of storage of glycogen or lipid. Immunohistochemical staining with antibodies raised against three different dystrophin peptides revealed proper subcellular localization of dystrophin at the sarcolemma of all myofibers, but the intensity of the stain was decreased. Western blot analysis using the same antibodies revealed normal dystrophin in size, but showed the reduced amount of the protein. The DNA obtained from the patient's peripheral leukocyte showed a deletion of the dystrophin gene including exon 45 by using PCR technique. Though the detailed size and portion of the deleted gene are not ascertained, the deletion in this case may not severely affect the function of dystrophin, unlike cases of Duchenne or Becker muscular dystrophy. Dystrophin analysis is useful for the etiologic diagnosis in cases of myalgia and high CKemia."
