Duchenne and Becker Muscular Dystrophy (DMD & BMD) are X-linked neuromuscular diseases of childhood resulting from a defect in the dystrophin gene. Deletion of one or more exons in the dystrophin gene may cause DMD/BMD. This assay detects deletions in all 79 exons of the dystrophin gene in both males & females. This test is indicated for males with a clinical diagnosis or symptoms of Duchenne or Becker muscular dystrophy and for female relatives.
