摘要 目的探讨eNOS、ET-2基因多态性与高血压的相关性。方法采用病例-对照相关性研究策略,选择三代居住在云南的汉族作为研究对象,用基因芯片检测技术,对100例高血压患者及97例健康对照者进行eNOS Glu298Asp(EE、ED、DD)、ET-2A985G(AA、AG、GG)位点基因多态性检测。用OddRatio估计相对危险度。结果云南汉族97例健康人群中:(1)eNOS Glu298Asp位点的EE、ED、DD基因型频率分别是0.845、0.144、0.011;E和D等位基因频率分别是0.918、0.082。(2)ET-2A985G位点的AA、AG、GG基因型频率分别是0.020、0.258、0.722;A和G等位基因频率分别是0.149、0.851。(3)云南汉族100例高血压患者中,ET-2A985G(AA、AG、GG)位点基因型多态性频率与对照组比较,差异无统计学意义。但ET-2A985G位点G等位基因频率(0.925)与对照组(0.851)比较,差异有统计学意义(χ2=5.507、P=0.019),Odd Ratio=2.168(95%CI:1.123~4.184)。(4)eNOS Glu298Asp位点的DD基因型频率(0.01)与对照组(0.01)比较,差异无统计学意义。结论云南汉族中eNOS Glu298Asp突变对高血压的发生意义不大。ET-2A985G等位基因可能与高血压的易感性相关。
