摘要 目的观察血管紧张素原(AGT)基因单核苷酸多态性(SNPs)与妊娠高血压易感性的关系。方法选取2012年1月至2015年1月河源市妇幼保健院收治并确诊的妊娠高血压患者512例为研究组,对照组为同期在该院的健康体检者502例。应用基因组测序技术,检测AGT基因2个SNP位点(rs5050和rs36218431)基因型。选取rs5050和rs36218431不同基因型妊娠高血压患者外周血血清,采用酶联免疫吸附试验(ELISA法)测定不同基因型患者细胞上清液中AGT浓度。对比分析两组调查对象SNP等位基因频率和AGT浓度。结果两组2个AGT基因SNP位点的基因型分布遵守遗传平衡定律。其中rs5050位点存在GG、GA和AA基因型,研究组仅有rs2006765等位基因G频率(91.0%,919/1 010)显著高于对照组(83.0%,833/1 004),差异有统计学意义(P<0.05)。rs5050位点GG基因型外周血AGT浓度为(49±3)ng/L,显著高于AA/GA基因型的(31.0±2.5)ng/L,差异有统计学意义(P<0.05)。结论 AGT基因rs5050多态性与妊娠高血压易感性有显著相关性,其等位基因G是妊娠高血压的易感基因。而两组rs36218431比较,差异均无统计学意义(P>0.05)。rs5050多态性影响宿主外周血的AGT表达水平,在妊娠高血压过程中起重要作用。
