✦ Synopsis


The family of a male with Duchenne muscular dystrophy (DMD) and a deletion within the dystrophin gene has been studied. Polymerase chain reaction analysis of ectopic mRNA from peripheral blood T+B lymphocytes and the use of (CA) n repeat polymorphisms in and around the deleted region showed the proband's mother to be both a germline mosaic and a somatic mosaic for the deletion seen in her son. The mutation therefore occurred as a mitotic event early in embryogenesis.

The incidence of electrocardiographic features "typical" for the Duchenne progressive muscular dystrophy (PMD) was investigated in 191 carriers: 136 mothers and 55 daughers. The typical PMD pattern was seen in 6.6% of the mothers, and a pattern similar to that observed in PMD in 2.9%. Among daughter

We present the results of an international collaborative study aimed at estimating the ratio of male to female mutation rates in Duchenne muscular dystrophy based on the method of C. MΓΌller and T. Grimm. With a sample size of 295, this ratio is found to be very close to 1, thus giving evidence for e
