假肥大型进行性肌营养不良为一进行性肌肉变性疾病。本病影响儿童,表现近端肌肉力弱、萎缩和腓肠肌肥大,常合并关节挛缩,心肌损害,患儿12岁后生活不能自理,25岁以前死亡,对家庭对社会造成严重的问题。本病系性连隐性遗传,少数病例报告有常染色体隐性遗传。在临床遇到的病人常缺乏明显的家族史。为了探讨本病的遗传特点,我们总结80例假肥大型肌营养不良(以 Duchenne muscular dystrophy is a progressive muscle degenerative disease. The disease affects children, the performance of the proximal muscular weakness, atrophy and gastrocnemius hypertrophy, often associated with joint contracture, myocardial damage, children can not take care of themselves after the age of 12, died before the age of 25, causing serious problems for families to society. The disease with recessive inheritance, a few cases of autosomal recessive inheritance. In clinical encounter patients often lack a clear family history. In order to explore the genetic characteristics of this disease, we conclude 80 cases of Duchenne muscular dystrophy (to
