A novel mutation of dystrophin in a Becker muscular dystrophy family with severe cardiac involvement: from genetics to clinicopathology

We identified a novel dystrophin mutation (p.1667 del Ala), resulting in BMD-associated cardiomyopathy that demonstrated the pathological features of significant fibrofatty replacement in the sub-epicardial layer of the ventricle; further, the high-throughput sequencing is helpful for making an early diagnosis of BMD.
