In people, the most common forms include the X-linked Duchenne and Becker muscular dystrophies associated with mutations in the dystrophin gene (DMD), and the limb-girdle muscular dystrophies (LGMD) associated with autosomal dominant (LGMD1) or autosomal recessive (LGMD2) mutations in several genes [1, 2]. Here, DMD is linked to Duchenne muscular dystrophy.
