The aim of this study was to establish a direct nested PCR combined with sequencing to detect this locus. Methods: The target fragment containing the C-1019G locus of the 5-HT1A gene was amplified by direct nested PCR using crude processed oral epithelial cells, and the PCR product was genotyped by Sanger sequencing. Results: PCR products of expected size were amplified from all the samples tested, and the sequencing peaks were clear. Conclusion: A direct nested PCR combined with sequencing method was successfully established to identify the genotypes of 5-HT1A gene, which has good prospects for application.展开更多
5-HT1A基因编码5-羟色胺(血清素)的G蛋白偶联受体(属于5-羟色胺受体亚家族)。C-1019G多态位点是5-HT1A基因启动子区一个重要的功能性多态位点,人群中存在3种基因型即CC、CG、GG,它与个体的恋爱关系及抑郁症、焦虑症等精神疾病密切相关...5-HT1A基因编码5-羟色胺(血清素)的G蛋白偶联受体(属于5-羟色胺受体亚家族)。C-1019G多态位点是5-HT1A基因启动子区一个重要的功能性多态位点,人群中存在3种基因型即CC、CG、GG,它与个体的恋爱关系及抑郁症、焦虑症等精神疾病密切相关。本文对5-HT1A基因C-1019G多态位点的相关机制、检测方法、研究进展等进行综述。The 5-HT1A gene encodes a G protein-coupled receptor for serotonin, which belongs to the 5-hydroxytryptamine receptor subfamily. C-1019G polymorphism is an important functional poly-morphism in the promoter region of 5-HT1A gene. There are three genotypes (CC, CG and GG) in the population, which are closely related to individual’s romantic relationship and mental disorders such as depression and anxiety. In this paper, the mechanism, detection methods and research progress of C-1019G polymorphism of 5-HT1A gene were reviewed.展开更多
