摘　　要：肥厚型心肌病(Hypertrophic cardiomyopathy,HCM)是以左心室及室间隔不对称肥厚为基本特征的原发性心肌病,其发病率约为0.2%,是青少年和运动员心源性猝死的最常见原因。HCM的发病年龄、发病程度和猝死风险等临床表型具有多样性,通常呈常染色体显性遗传。目前已报道的HCM相关突变超过900种,主要定位在β肌球蛋白重链基因、肌球蛋白结合蛋白C基因、心脏肌钙蛋白T基因等13个心脏肌节蛋白基因;另一方面,越来越多的研究显示线粒体基因突变与HCM发生相关。文章在简单介绍HCM形态学特征及临床表型的基础上,着重综述了HCM的致病分子机制及其最新研究进展。Hypertrophic Cardiomyopathy（HCM） is a primary cardiac disorder characterized by asymmetric thickening of the septum and left ventricular wall.HCM affects 1 in 500 individuals in the general population,and it is the most common cause of sudden death in the young and athletes.The clinic phenotype of HCM is highly variable with respect to age at on-set,degree of symptoms,and risk of sudden death.HCM is usually inherited as a Mendelian autosomal dominant trait.To date,over 900 mutations have been reported in HCM,which were mainly located in 13 genes encoding cardiac sarcomere protein,e.g.,MYH7,MYBPC3,and TnT.In addition,more and more mitochondrial DNA mutations were reported to be associated with the pathogenesis of HCM.Based on the description of the clinical phenotype and morphological character-istics,this review focuses on the research in the molecular pathogenic mechanism of HCM and its recent advances.
