Mutations in the genes encoding collagen VI (COL6A1, COL6A2, and COL6A3) cause Bethlem myopathy (BM) and Ullrich congenital muscular dystrophy (UCMD), two conditions which were previously believed to be completely separate entities. BM is a relatively mild dominantly inherited disorder characterised by proximal weakness and distal joint contractures. UCMD was originally described as an autosomal recessive condition causing severe muscle weakness with proximal joint contractures and distal hyperlaxity. Here we review the clinical phenotypes of BM and UCMD and their diagnosis and management, and provide an overview of the current knowledge of the pathogenesis of collagen VI related disorders.
编码胶原蛋白VI(COL6A1、COL6A2和COL6A3)的基因突变会导致贝斯勒肌病(BM)和乌尔里希先天性肌营养不良症(UCMD),这两种病症以前被认为是完全不同的实体。BM是一种相对较轻的显性遗传性疾病,其特征为近端肌无力和远端关节挛缩。UCMD最初被描述为一种常染色体隐性疾病,会导致严重的肌无力,并伴有近端关节挛缩和远端关节过度松弛。在此,我们回顾了BM和UCMD的临床表型及其诊断和治疗,并概述了目前关于胶原蛋白VI相关疾病发病机制的知识。
