Lancet Psychiatry:影响抗精神病药治疗效果的基因因素

2018-03-02 zhangfan MedSci原创

研究发现了一系列与突触功能、神经递质受体和精神分裂症风险相关的基因,这些基因与抗精神病药物的治疗反应有关。这一发现提高了对精神病治疗反应机制的理解,对指导精神分裂症患者个体化治疗提供了依据

抗精神病药物可以改善精神分裂症症状,减少复发频率,但不同患者对相关药物的治疗反应差异十分显著。目前学术界对与抗精神病药治疗反应相关的基因因素知之甚少。近日研究人员对精神分裂症患者抗精神病药物治疗反应进行了全基因组关联研究。

研究在中国32个精神病治疗中心开展,患者接受奥氮平、利培酮、奎硫平、阿立哌唑、齐拉西酮、氟哌啶醇或奋乃静治疗。治疗效果进行阳性-阴性症状评估,考察与治疗效果相关的单核苷酸多态性。基因相关性验证工作在其他5所治疗中心开展。

开发队列包含2413名患者,验证队列包含1379名患者。开发队列发现了3个与治疗响应相关的基因,分别是MEGF10基因rs72790443, SLC1A1基因rs1471786以及PCDH7基因rs9291547。研究结果在验证队列中得到确证。2个队列中,总计发现了5个新型基因位点与抗精神病药治疗响应相关,分别为MEGF10-rs72790443、SLC1A1- rs1471786、PCDH7-rs9291547、CNTNAP5- rs12711680以及TNIK- rs6444970。亚组分析中 CACNA1C- rs2239063与奥氮平治疗响应相关,SLC1A1-rs16921385与利培酮响应相关而CNTN4- rs17022006与阿立哌唑治疗响应相关。

研究发现了一系列与突触功能、神经递质受体和精神分裂症风险相关的基因,这些基因与抗精神病药物的治疗反应有关。这一发现提高了对精神病治疗反应机制的理解,对指导精神分裂症患者个体化治疗提供了依据。
