Charcot-Marie-Tooth disease (CMT) is one of the most common inherited peripheral neuropathies. CMT patients typically show slowly progressive muscle weakness and sensory loss in a distal dominant pattern in childhood. The diagnosis of CMT is based on clinical symptoms, electrophysiological examinations, and genetic testing. Advances in genetic testing technology have revealed the genetic heterogeneity of CMT; more than 100 genes containing the disease causative mutations have been identified. Because a single genetic alteration in CMT leads to progressive neurodegeneration, studies of CMT patients and their respective models revealed the genotype-phenotype relationships of targeted genes. Conventionally, rodents and cell lines have often been used to study the pathogenesis of CMT. Recently, has also attracted attention as a CMT model. In this review, we outline the clinical characteristics of CMT, describe the advantages and disadvantages of using in CMT studies, and introduce recent advances in CMT research that successfully applied the use of , in areas such as molecules associated with mitochondria, endosomes/lysosomes, transfer RNA, axonal transport, and glucose metabolism.
腓骨肌萎缩症(Charcot-Marie-Tooth disease,CMT)是最常见的遗传性周围神经病之一。CMT 患者在儿童期通常表现为以远端为主的进行性肌无力和感觉丧失。CMT 的诊断基于临床症状、电生理检查和基因检测。遗传检测技术的进步揭示了 CMT 的遗传异质性;已经确定了 100 多个包含疾病致病突变的基因。由于 CMT 中单个遗传改变导致进行性神经退行性变,对 CMT 患者及其各自模型的研究揭示了靶向基因的基因型-表型关系。传统上,啮齿动物和细胞系常用于研究 CMT 的发病机制。最近, 也作为 CMT 模型引起了关注。在这篇综述中,我们概述了 CMT 的临床特征,描述了在 CMT 研究中使用 的优缺点,并介绍了最近在 CMT 研究方面的进展,成功应用了 来研究与线粒体、内体/溶酶体、转移 RNA、轴突运输和葡萄糖代谢相关的分子。
