Background:
Becker muscular dystrophy (BMD) is an X-linked neuromuscular disease
caused by dystrophin gene mutation. It usually occurs in male, while
females are usually the carriers of the abnormal chromosome. Patients
might present with limb weakness and muscle atrophy with a chronic
progressive disease course. In addition to skeletal muscle involvement,
BMD can also be complicated with cardiac injury. In this case report, we
presented the clinical data of a male patient with BMD complicated with
dilated cardiomyopathy (DCM) and survey results of this pedigree.
