Keyword:  海洛因依赖受体多巴胺D2多态性限制性片段长度等位基因;
Abstract: 目的探讨海洛因依赖与多巴胺D2受体基因的相关性.方法应用聚合酶链反应-限制性片段长度多态性分析技术,检测302例海洛因依赖者和177名正常对照者的D2受体基因-141C Ins/Del 多态性的基因型和等位基因频率.结果共检测出三种基因型:纯合子-141C Del/Del(304 bp、304 bp)、杂合子-141C Ins/Del(304 bp、160 bp、144 bp)、纯合子-141C Ins/Ins(160 bp、144 bp).海洛因依赖组的-141C Ins/Del 多态性的基因型频率与对照组的差异无显著性(χ2=5.33,P=0.07),但海洛因依赖组-141C Del等位基因频率(16.6%)高于对照组(11.0%;χ2=5.37,P=0.02).结论 D2受体基因-141C Ins/Del多态性可能与海洛因依赖的易感性相关.
