摘要
目的探讨焦虑症与儿茶酚邻甲基转移酶基因多态性的相关性。方法运用聚合酶链反应技术检测88例焦虑症患者和87例健康对照儿茶酚邻甲基转移酶基因多态性,并加以对照分析。结果患者组高活性H型(G)和低活性L型(A)等位基因频率分别为81%、19%,对照组分别为67%和33%,两组间的差异均有显著性(P<0.05);患者组G/G、G/A、A/A基因型分布频率分别为61%、39%、0,对照组分别为40%、53%和7%,除G/A基因型在两组间差异无显著性(P>0.05)外,G/G和A/A基因型在两组间差异均有显著性(P<0.05);焦虑症亚型间各基因型、等位基因频率比较的差异均无显著性(P>0.05)。结论COMT的G等位基因、G/G基因型可能是焦虑症的危险因素之一,A等位基因、A/A基因型可能是焦虑症的保护基因之一;焦虑症两种亚型间COMT多态性无显著性差异。
