Genome Med:研究对2572名肺动脉高血压患者进行外显子组测序,发现了新的危险基因和机制

I型肺动脉高压(PAH)是一种罕见的疾病,尽管最近其治疗有所进展,但死亡率很高。肺动脉血管的病理性重塑导致肺动脉压升高、右心室肥大和心力衰竭。骨形态遗传蛋白受体2型和其他危险基因的突变会导致疾病的发生

I型肺动脉高压(PAH)是一种罕见的疾病,尽管最近其治疗有所进展,但死亡率很高。肺动脉血管的病理性重塑导致肺动脉压升高、右心室肥大和心力衰竭。骨形态遗传蛋白受体2型和其他危险基因的突变会导致疾病的发生,但绝大多数非家族性的病例在基因上仍未确定。

 

为了确定新的风险基因,我们在一个大型队列中进行了外显子组测序,该队列来自国家生物样本和数据库的PAH生物库(PAH生物库,n = 2572)。然后,我们进行了罕见的缺失性变异鉴定,然后进行基于病例对照的基因关联分析。为了控制人口结构,我们只使用了不相关的欧洲病例(n = 1832)和对照组(n = 12,771)进行关联测试。经验性P值通过交替分析确定,并通过Bonferroni校正多重检验的显著性阈值确定。

 

结构发现,组织卡力克蛋白1(KLK1)和γ-谷氨酰羧化酶(GGCX)被确定为特发性PAH(IPAH)的新的候选危险基因,具有全基因组意义。与骨形态基因受体2型变异携带者相比,变异携带者的平均发病年龄较晚,疾病表型也相对温和。此外,研究还证实了最近报道的生长分化因子(GDF2)与IPAH的全基因组关联,并进一步将T-box 4(TBX4)与儿童发病的PAH联系起来。

 

总之,报告了新型基因KLK1和GGCX与IPAH的稳健关联,分别占PAH生物库病例的0.4%和0.9%。这两个基因在血管血流动力学和炎症中起着重要作用,但之前没有在PAH中被发现。这些数据提示了这种致命性血管病的新基因、致病机制和治疗靶点。
