JACC:TSR1基因突变与自发性冠脉夹层呈相关性

2019-07-23 不详 MedSci原创

自发性冠脉夹层(SCAD)定义为除去医源性和外伤的冠脉壁破裂。近几十年,人们对SCAD的诊断、预后和治疗的认识均有了很大的进步,但其发病原因尚不清楚。本研究的目的旨在中国汉族人群中探究与SCAD发展相关的基因。本研究纳入了85例SCAD患者和296名非SCAD对照,并对其进行了全外显子测序和一代测序验证。分析结果显示,通过两种分析方法筛出了4个与SCAD呈相关性的基因(p < 5.41 ×

自发性冠脉夹层(SCAD)定义为除去医源性和外伤的冠脉壁破裂。近几十年,人们对SCAD的诊断、预后和治疗的认识均有了很大的进步,但其发病原因尚不清楚。本研究的目的旨在中国汉族人群中探究与SCAD发展相关的基因。

本研究纳入了85例SCAD患者和296名非SCAD对照,并对其进行了全外显子测序和一代测序验证。分析结果显示,通过两种分析方法筛出了4个与SCAD呈相关性的基因(p < 5.41 × 10-5),其中相关性最强的基因为TSR1,所有的TSR1基因变异要么在不同物种间高度保守,要么导致蛋白质合成提前终止。另外,TSR1蛋白能在人类冠状动脉中检测出表达。

研究结果显示,在中国自发性冠脉夹层患者中,TSR1基因被认为是候选致病基因,加深了对SCAD的认识。
