this study determines the value of linkage analysis using six rflp markers for carrier detection and prenatal diagnosis in familial dmd/bmd cases and their family members for the first time in the iranian population. we studied the dystrophin gene in 33 unrelated patients with clinical diagnosis of dmd or bmd. subsequently, we determined the rate of heterozygosity for six intragenic rflp marker...

background and objective: becker muscular dystrophy (bmd) is a subtype of dystrophinopathies and designated as “mild form of dystrophinopathy”. the frequency rate of the disease is 1:18000 to 1:30000 in different populations and the symptoms are presented at about 8-9 years of age. the diagnostic panel composed of serum ceratin kinase (sck) measurement, electromyography (emg), and as a major co...

We describe a man with Becker muscular dystrophy whose weakness was minimal in contrast to that of his more severely affected nephews. This man had a Klinefelter karyotype (47,XXY) and his mild symptoms may be attributed to him being heterozygous for the muscular dystrophy gene. This is the first report of a person with both Klinefelter's syndrome and Becker muscular dystrophy. This combination...

Duchenne muscular dystrophy is the most common and severe form of the childhood muscular dystrophies. The disease is typically diagnosed between 3 and 7 years of age and follows a predictable clinical course marked by progressive skeletal muscle weakness with loss of ambulation by 12 years of age. Death occurs in early adulthood secondary to respiratory or cardiac failure. Becker muscular dystr...

Duchenne and Becker muscular dystrophies are X-linked allelic disorders in which the association of central nervous system dysfunction, typically in the form of mental retardation, is a well recognized feature. They are both due to mutations in the dystrophin gene, whose corresponding protein products are expressed both in the muscle and central nervous system. We have observed an increased fre...

Rimmed vacuoles in myofibers are thought to be due to the accumulation of autophagic vacuoles, and can be characteristic in certain myopathies with protein inclusions in myofibers. In this study, we performed a detailed clinical, molecular, and pathological characterization of Becker muscular dystrophy patients who have rimmed vacuoles in muscles. Among 65 Becker muscular dystrophy patients, we...

OBJECTIVE To investigate the prevalence, age distribution, and spectrum of cardiac involvement in a cohort of patients with Becker muscular dystrophy. DESIGN A prospective non-invasive study with clinical, electrocardiographic, and echocardiographic assessment. PATIENTS 19 patients (age range 16-41 years) with Becker muscular dystrophy attending the Muscle Clinic at Hammersmith Hospital and...

et. al, 1968/1969) and give an estimate of 0-23 for the recombination fraction with 9500 confidence limits of 0-13 to 0 43. These results confirm the linkage relationships between deutan colour blindness and Becker muscular dystrophy but since the loci for Duchenne muscular dystrophy and colour blindness are not within measurable distance of each other these results indicate that the Becker and...
