Functional capacity of dystrophins carrying deletions in the N-terminal actin-binding domain.

Duchenne muscular dystrophy and Becker muscular dystrophy (BMD) are caused by mutations in the dystrophin gene. Although many in-frame deletions in the dystrophin gene lead to mild cases of BMD, truncations within the N-terminal actin-binding domain (ABD1) typically decrease dystrophin expression and lead to more severe cases of BMD. Because of the large… CONTINUE READING
