Molecular biology of duchenne and Becker's muscular dystrophy: Clinical applications

Abstract
Recent advances in molecular genetics have led to the isolation of the gene defective in patients with Duchenne and Becker's muscular dystrophy and the characterization of its protein product, dystrophin. In this communication, the developments culminating in the identification of the Duchenne muscular dystrophy locus are reviewed. The practical applications of this research and pitfalls that limit prenatal diagnosis and carrier detection are discussed.
