摘要 目的探讨精神分裂症患者5-羟色胺2A受体(5-hydroxytryptamine 2A receptor,5-HTR2A)基因多态性与抗精神病药物治疗反应的关系。方法 300例精神分裂症患者使用氯氮平(n=132)、氯丙嗪(n=78)、利培酮(n=90)中任一种治疗8周,以阳性与阴性症状量表(PANSS)评定疗效;以SNaPshot单核苷酸多态性(sin-gle nucleotide polymorphism)技术检测5-HTR2A基因rs6313和rs6311多态性。结果氯丙嗪总疗效有效组与无效组相比,rs6311等位基因A、G的分布差异有统计学意义(2=3.939,P=0.047);利培酮改善阴性症状有效组与无效组相比,rs6313基因型T/T与T/C、C/C的分布差异有统计学意义(2=6.484,P=0.039),而其等位基因T、C的分布差异也有统计学意义(2=9.899,P=0.002)。结论 5-HTR2A基因rs6313和rs6311多态性可能与抗精神病药物治疗精神分裂症的临床疗效有关,rs6311等位基因A和rs6313基因型T/T及等位基因T分别是氯丙嗪总体疗效好和利培酮阴性症状疗效好的预测因子。
