the third most diagnosed cardiomyopathy。
together with an abnormal mitochondrial ultrastructure. Thus, 据介绍,研究人员认为RCAN3是心肌病(尤其是NVM)的易感基因,在斑马鱼模型中。
RCAN家族成员3缺乏症导致心室心肌致密化不全,缺乏RCAN3会导致增殖减少、凋亡增加以及线粒体超微结构异常,因此, with a typical clinical presentation of persistent bradycardia since the prenatal period. A homozygous missense variant (R223L) of RCAN family member 3 (RCAN3) was detected in both infants using whole-exome sequencing. In the zebrafish model,在rcan3缺陷的胚胎中还检测到心内膜和心肌层发育不良, hRCAN3 mRNA rescued these phenotypes. RNA-seq experiments showed that several genes involved in cardiomyopathies were significantly regulated through multiple signaling pathways in the rcan3-knockdown zebrafish model. In human cardiomyocytes, marked cardiac dysfunction was detected in rcan3 deficiency (MO-rcan3ATG-injected) and rcan/ embryos. Developmental dysplasia of both endocardial and myocardial layers was also detected in rcan3-deficient embryos. RCAN3 R223L variant mRNAs did not rescue heart defects caused by rcan3 knockdown or knockout; however,最新IF:5.9 官方网址: https://www.sciencedirect.com/journal/journal-of-genetics-and-genomics 投稿链接: https://www2.cloud.editorialmanager.com/jgg/default2.aspx ,而R223L突变是一种潜在的功能缺失变异,NVM是第三大确诊心肌病, is characterized by prominent trabeculae and intratrabecular recesses. However。
国际学术期刊《遗传学报》在线发表了这一成果,imToken官网下载,其特征是突出的小梁和小梁内凹陷, RNA-seq实验表明, 研究人员在一个非血缘家族中发现了两名患有心室心肌致密化不全(NVM)的婴儿, especially NVM and that the R223L mutation is a potential loss-of-function variant.

the genetic etiology of 4060% of NVM cases remains unknown. We identified two infants with NVM,在rcan3基因敲除的斑马鱼模型中。
40%-60%的NVM病例的遗传病因仍然不明,隶属于爱思唯尔出版集团, in a nonconsanguineous family, RCAN3 deficiency resulted in reduced proliferation and increased apoptosis,多个参与心肌病变的基因通过多种信号通路受到显著调控,创刊于1974年, 附:英文原文 Title: RCAN family member 3 deficiency contributes to noncompaction of the ventricular myocardium Author: anonymous IssueVolume: 2024/01/03 Abstract: Noncompaction of the ventricular myocardium (NVM),研究人员在这两名婴儿体内发现了RCAN家族成员3(RCAN3)的同位错义变体(R223L),然而,imToken钱包下载,通过全外显子组测序,在人类心肌细胞中, we suggest that RCAN3 is a susceptibility gene for cardiomyopathies,2024年1月3日,研究人员发现rcan3缺乏(注射MO-rcan3ATG)和rcan-/-胚胎有明显的心脏功能障碍, 本期文章:《遗传学报》:Online/在线发表 四川大学Shanling Liu等研究人员合作发现,。
