[Molecular biology in diagnosis and detection of deletion in Duchenne muscular dystrophy].

For the purpose of carrier identification and genetic counselling we investigated deletions of the Duchenne muscular dystrophy (DMD) gene in three families of patients with Duchenne muscular dystrophy. Using a limited number of probes of the DMD cDNA in Southern blots, we detected a deletion in only one patient. Additional methodology is necessary to warrant reliable identification of carriers and exact prenatal diagnosis.
