Effective strategy for prenatal prediction of Duchenne and Becker muscular dystrophy.
Deletions in the gene sequence for Duchenne (DMD) and Becker (BMD) muscular dystrophy were detected in affected males with four cDNA probes, Cf56a, Cf23a, Ca1A, and Cf27. Most of the deletions were seen with only one of the probes. Cf23a detected all BMD deletions seen with Cf56a and some that were not. The same markers also detected restriction fragment length polymorphisms for those cases where deletions were not evident. The probes were also used successfully for prenatal diagnosis in two families each with two DMD affected males. In DMD families successive application of probes Cf56a, Ca1A, and Cf27 will give a 70% chance of detecting the mutation. BMD families should first be screened with the Cf23a probe.
