The milder form of dystrophinopathy, Becker muscular dystrophy (BMD), also caused by mutations in the DMD gene, presents with a wider range of symptoms from limb–girdle weakness with loss of ambulation to a less severe course of disease with myalgias in youth and adulthood and is typically associated with a residual abundance of the dystrophin protein [5]. The gene discussed is DMD; the disease is neuromuscular disease caused by qualitative or quantitative defects of dystrophin.
