DMD (Dystrophin) variants and mutations

DMD (also known as Dystrophin) is a human protein-coding gene encoding a dystrophin protein. Its dystrophin product mechanically links the actin cytoskeleton of muscle fibers to the extracellular matrix and stabilizes the sarcolemma during contraction. Severe loss causes Duchenne muscular dystrophy, while variants preserving partial function more often cause Becker muscular dystrophy. This analysis covers 5,876 DMD variants and mutations. Of these, 61% have computational variant effect predictions. Disease context includes Duchenne muscular dystrophy, Becker muscular dystrophy, and dilated cardiomyopathy 3B. Example DMD variants include M1L, L2F, and W3*.
