摘要 目的:分析 DNA 双链损伤修复基因 NBS1的 Glu185Gln 单核苷酸多态性与广东地区汉族妇女的宫颈癌遗传易感性的关系。方法:采用聚合酶链式反应-限制性片段长度多态性( PCR-RFLP)技术,对139例宫颈癌患者及264例健康对照者的 NBS1 Glu185Gln 多态位点进行基因分型,比较病例组与对照组的基因型分布情况,并采用非条件 logistic 回归方法分析该多态位点与宫颈癌发生的关系。结果:携带 GG 基因型的个体患宫颈癌的风险显著增加(OR =2.231,95% CI =1.247-3.991,P =0.007),并且 G 等位基因增加个体患宫颈癌风险的趋势在Ⅰ期的宫颈癌患者中更显著(GG vs CC:调整后 OR=3.703,95% CI=1.559-8.798,P =0.003)。结论:NBS1基因的 Glu185Gln 多态位点与广东地区汉族妇女宫颈癌的发生相关,G 等位基因可能是影响宫颈癌易感的风险因素。
