该基因的基因组范围大于2 Mb，编码一个含有N端肌动蛋白结合域和多个谱蛋白重复序列的大蛋白编码的蛋白质形成了抗肌萎缩蛋白糖蛋白复合物（dgc）的一个组成部分，dgc连接细胞内骨架和细胞外基质。该基因位点的缺失、重复和点突变可能导致杜氏肌营养不良（DMD）、贝克肌营养不良（BMD）或心肌病。选择性启动子的使用和选择性剪接导致该基因的许多不同的转录变体和蛋白质亚型[由RefSeq提供，2016年12月]
This gene spans a genomic range of greater than 2 Mb and encodes a large protein containing an N-terminal actin-binding domain and multiple spectrin repeats. The encoded protein forms a component of the dystrophin-glycoprotein complex (DGC), which bridges the inner cytoskeleton and the extracellular matrix. Deletions, duplications, and point mutations at this gene locus may cause Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD), or cardiomyopathy. Alternative promoter usage and alternative splicing result in numerous distinct transcript variants and protein isoforms for this gene. [provided by RefSeq, Dec 2016]
