Genetic analysis of the Duchenne muscular dystrophy gene.
Molecular biology techniques have changed the way in which we now consider a patient with Duchenne muscular dystrophy or Becker muscular dystrophy. Using cDNA probes, it has been shown that approximately 65% of the patients with Duchenne muscular dystrophy or Becker muscular dystrophy have gene deletions. The identification of a deletion allows the disease to be confirmed by noninvasive DNA testing. Furthermore, the identification of the gene defect can help distinguish Becker muscular dystrophy from other clinically similar neuromuscular disorders. Most importantly, the elucidation of the gene defects has resulted in the application of direct carrier and prenatal diagnostics.
