摘要 目的 探讨肿瘤坏死因子-α(tum or necrosis factor- alpha,TNF-α)基因启动子- 30 8G>A、- 85 0 C>T多态性与妊娠期高血压疾病的相关性。方法 应用聚合酶链反应-限制性片段长度多态性技术检测10 6例患者和10 8名健康孕妇的TNF- α基因启动子- 30 8G>A、- 85 0 C>T多态性。对两组之间的基因型频率和等位基因频率进行比较。结果 TNF-α基因启动子- 30 8位点TNF2等位基因频率和TNF2 / 1基因型频率在病例组明显升高(P<0 .0 5 )。- 85 0位点T等位基因频率和CT+TT基因型频率在对照组明显升高,差异有统计学意义(P<0 .0 5 )。由这两个多态性位点组成的不同基因型中,病例组TNF2 / 1CC基因型频率明显高于对照组,差异有统计学意义(P<0 .0 5 ) ,而TNF1/ 1TT基因型频率在对照组明显增高,差异有统计学意义(P<0 .0 5 )。结论 TNF- α- 30 8、- 85 0位点多态性与妊娠期高血压疾病相关,其中TNF- α基因- 30 8位点的突变是危险因素,- 85 0位点的突变可能是保护性因素。TNF2 / 1CC基因型可能是妊娠期高血压疾病的易感基因型。
