Within that group, dystrophinopathies are the most common, which includes Duchenne muscular dystrophy, or DMD, and Becker muscular dystrophy, both of which result from mutations in the dystrophin gene.

些功能紊乱中，良疾病是最常见的，包括Duchenne型肌良（DMD）和Becker型肌良（BMD）；者都是由抗肌萎缩蛋白基因突变导致的。

Genetic testing ultimately identified a pathogenic dystrophin DMD gene deletion consistent with her being a symptomatic carrier of Duchenne's muscular dystrophy, with skeletal muscle and cardiac involvement.

基因检测最终揭示了一个致病性的肌良蛋白基因（DMD）缺失， 与她作为杜兴氏肌良症的症状携带者身份相符，且该病已累及骼肌和心脏。
