JAHA:中国肥厚型心肌病患者FHOD3基因的变异谱分析

2021-02-16 MedSci原创 MedSci原创

该研究的结果表明FHOD3基因是HCM的致病基因,而FHOD3候选突变体是HCM患者因心血管死亡和全因死亡的独立危险因素。

甲酸同系物2结构域3(FHOD3)基因最近被确定为肥厚型心肌病(HCM)的致病基因。但是,FHOD3基因变异的致病性仍有待评估。近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,该研究旨在分析HCM患者和对照人群中FHOD3变异谱,并探讨其与疾病之间的相关性。

研究人员使用1000名HCM患者和761名无HCM对照者的全外显子组测序数据对FHOD3基因进行了遗传分析,总共确定出37个FHOD3候选突变体,包括25个错义变异体和2个截短变异体。

详细而言,研究人员在33例HCM患者中检测到27个候选突变体(3.3%),显著高于12例对照者(3.3% vs. 1.6%;比值比为2.13;P<0.05)。基于家族,研究人员在4例患者中确定了一个截短变异体(c.1286+2delT)作为因果变异体。此外,FHOD3候选突变体发生心血管死亡和全因死亡的风险明显更高(调整后的风险比[HR]为3.71;95%CI为1.32-8.59;P=0.016;调整后的HR为3.02;95%CI为1.09-6.85;P=0.035)。

由此可见,该研究的结果表明FHOD3基因是HCM的致病基因,而FHOD3候选突变体是HCM患者因心血管死亡和全因死亡的独立危险因素。
