Abstract
目的 探讨脑源性神经营养因子(brain-derived neurotrophic factor,BDNF)基因与神经营养性酪氨酸激酶受体2型(neurotrophic tyrosine kinase receptor type 2,NTRK2)基因交互作用与青年自杀未遂行为的关系.方法 使用IMLDRtm多重SNP分型技术对病例组(70例自杀未遂青年人)和对照组(112例健康青年人)的BDNF基因1个多态性位点rs1491851和NTRK2基因3个多态性位点rs1147198、rs11140800、rs1565445进行分型,采用广义多因子降维法(generalized muhifactor dimensionality reduction,GMDR)分析基因-基因交互作用.结果 在病例组与对照组中,BDNF rs1491851、NTRK2 rs1147198、rs11140800、rs1565445基因型频率与等位基因频率的分布差异均无统计学意义(P>0.05).GMDR分析结果显示,BDNF基因与NTRK2基因的2~4阶交互作用,分别为两位点模型(rs1491851、rs1147198)、三位点模型(rs1491851、rs1147198、rs11140800)和四位点模型(rs1491851、rs1147198、rs11140800、rs1565445).其中四位点模型(rs1491851、rs1147198、rs11140800、rs1565445,测试样本精度为0.632 5,交叉一致性检验为10/10,1 000次置换检验P值为0.032~0.033)为最佳模型.结论 BDNF基因与NTRK2基因存在交互作用,可能与青年自杀未遂行为相关.
