摘要 目的:研究X线修复交叉互补基因3(XRCC3)Thr241Met多态性位点在广东人群中的分布,并分析其多态性与宫颈癌发病风险的关系。方法:采用病例-对照研究方法,应用PCR-RFLP检测158例宫颈癌患者及年龄相匹配的164例正常人群XRCC3Thr241Met多态性位点基因型及等位基因,并分析该位点与宫颈癌发病风险的关系。结果:Thr241Met基因型和等位基因频率在病例组和对照组中的分布差异有统计学意义(P<0.05),等位基因Met可能增加个体患宫颈癌的风险(OR=1.983,95%CI=1.364~2.883,P=0.000),提示Thr241Met多态性可能与个体患宫颈癌风险相关;但Thr241Met多态性与宫颈癌患者临床病理特征无关。结论:Thr241Met多态性可能与宫颈癌风险相关,Met等位基因可增加个体患宫颈癌的风险,但与宫颈癌临床病理特征无关。
