    Abstract:
    The ability to map disease loci using restriction fragment length polymorphisms (RFLPs) identified by DNA probes has revolutionized molecular genetics. Duchenne and Becker muscular dystrophies have been shown to be localized within the same very small region of Xp21 on the human X chromosome. The mutation itself should soon be identified at the DNA level, which will permit a detailed analysis of the molecular defect at the biochemical level. Rapid progress has also been made in the study of myotonic dystrophy on chromosome 19. DNA markers closely linked to the mutant locus have been identified, making antenatal diagnosis possible in informative families. Autosomal recessive muscular dystrophies are more difficult to study, but the means to localize even these mutations is being developed. The next decade should prove to be an exciting one for those involved in the molecular analysis and clinical management of human muscular dystrophies.
