摘要/Abstract

摘要： 腓骨肌萎缩症也称夏科-马利-杜斯氏病(Charcot-Marie-Tooth disease, CMT),是人类最常见的遗传性周围神经病之一,其遗传方式以常染色体显性遗传为主,也有部分呈常染色体隐性遗传或X连锁显性或隐性遗传。根据临床表型将CMT分为脱髓鞘型(CMT1)、轴突型(CMT2)和中间型（DI-CMT）。常染色体隐性遗传的CMT1(AR-CMT1,也称CMT4型)临床表现除了CMT常见的四肢远端进行性肌无力和萎缩,以及高足弓和爪形手外,常起病早,进展迅速,并有不同程度的感觉障碍和脊柱畸形(以脊柱侧凸为主)。近年来的研究显示,CMT4有11种亚型,其中有些亚型的致病机制较明确,有些亚型存在建立者突变,有些亚型还局限在临床描述和突变检出上。文章综述了CMT4的最新研究进展,包括各亚型的临床表现、致病机制和小鼠模型等。

Abstract: The Charcot-Marie-Tooth disease (CMT) is one of the most common human inherited peripheral neuropathies. The most common pattern of inheritance is autosomal dominant, with less often occurrence autosomal recessive and X-linked dominant/recessive inheritance. CMT is generally divided into three forms: demyelinating forms (CMT1), axonal forms (CMT2) and intermediate forms (DI-CMT). The autosomal recessive form (AR-CMT1 or CMT4) is accompanied by progressive distal muscle weakness and atrophy of the limbs, pes cavus and claw-like hands. In addition, CMT4 is also characterized by early onset, rapid progression, and varying degrees of sensory loss and spinal deformities (e.g. scoliosis). Recently, 11 subtypes of CMT4 have been identified. Some of these subtypes were clear in pathogenic mechanisms, some had founder mutation, but some still had limited clinical description and mutation analysis. In this review, we summarize the latest research progresses of CMT4, including genotypes and phenotypes, pathogenic mechanisms and mouse models.

Key words: Charcot-Marie-Tooth disease, CMT type 4, pathogenic mechanism, mouse model
