Idiopathic cardiomyopathy (ICM) is heterogeneous myocardial disease associated with functional abnormalities of cardiomyocytes. The aim of this study was to investigate the novel molecular pathogenesis of ICM caused by the genetic abnormalities. As the results, it was identified that (1) mutations in genes encoding CARP and Fukutin are associated with dilated cardiomyopathy (DCM), and (2)ZASP/Cypher anchors PGM1 to Z-disc under conditions of stress and the impaired binding of PGM1 to ZASP/Cypher might be involved in the pathogenesis of DCM.

特发性心肌病（ICM）是与心肌细胞功能异常相关的异质性心肌疾病。这项研究的目的是研究由遗传异常引起的新型ICM分子发病机理。如结果，据确定，（1）编码鲤鱼和富丁蛋白的基因中的突变与扩张的心肌病（DCM）以及（2）ZASP/CYPHER锚定在应激条件下PGM1与Z-DISC相关，并且PGM1的结合受损ZASP/Cypher可能参与DCM的发病机理。
