Endothelin-1 (ET-1) gene polymorphisms are implicated in pathogenesis of idiopathic pulmonary arterial hypertension.
We studied ET-1 (Lys198Asn and 3A/4A) and endothelin receptor A (ET) gene (His323His) polymorphisms in 123 subjects with pulmonary hypertension associated with rheumatic mitral valve disease (PH-MVD) and 123 healthy controls.
The mutant homozygous Asn/Asn genotype in Lys198Asn and T/T genotype in His323His polymorphism was more prevalent in the PH-MVD group. Presence of Asn/Asn genotype was significantly associated with an increased risk (odds ratio 3.9).
ET-1 and ET gene polymorphisms are prevalent in the PH-MVD group suggesting that they may predispose to the development of PH.
内皮素-1(ET-1)基因多态性与特发性肺动脉高压的发病机制有关。
我们研究了123例风湿性二尖瓣疾病相关肺动脉高压(PH-MVD)患者和123例健康对照者的ET-1(Lys198Asn和3A/4A)及内皮素受体A(ET)基因(His323His)多态性。
在PH-MVD组中,Lys198Asn突变纯合子Asn/Asn基因型和His323His多态性中的T/T基因型更为常见。Asn/Asn基因型的存在与风险增加显著相关(比值比3.9)。
ET-1和ET基因多态性在PH-MVD组中普遍存在,提示它们可能易导致PH的发生。
