BACKGROUND
Because Regnase-1, encoded by , suppresses the development of pulmonary arterial hypertension (PAH) by controlling pro-inflammatory cytokines, we aimed to identify variants in patients with PAH.
METHODS AND RESULTS
We analyzed whole-genome sequence data of patients with PAH to search for disease-associated variants. The Regnase-1 p.D426G variant was identified in 2 patients, 1 of whom presented with prominent infiltration of inflammatory cells in the lung. The protein level of the variant was decreased in vitro.
CONCLUSIONS
We identified a novel missense variant of that is directly involved in regulating inflammation in patients with PAH.
背景
由于由[具体基因名称]编码的Regnase-1通过控制促炎细胞因子来抑制肺动脉高压（PAH）的发展，我们旨在鉴定PAH患者中的[基因名称]变体。
方法与结果
我们分析了PAH患者的全基因组序列数据，以寻找与疾病相关的[基因名称]变体。在2例患者中鉴定出Regnase-1 p.D426G变体，其中1例患者肺部有明显的炎症细胞浸润。该变体的蛋白质水平在体外降低。
结论
我们鉴定出一种新的[基因名称]错义变体，它直接参与调节PAH患者的炎症。
