HTR1A（5-hydroxytryptamine receptor 1A），癌症关联基因，基因ID：3350，该基因编码5-羟色胺（5-羟色胺）的G蛋白偶联受体，属于5-羟色胺受体亚家族血清素与许多生理过程和病理条件有关该基因在小鼠中的失活导致行为与焦虑和应激反应的增加一致。该基因启动子突变与月经周期依赖性周期性发热有关[由RefSeq提供，2012年6月]This gene encodes a G protein-coupled receptor for 5-hydroxytryptamine (serotonin)， and belongs to the 5-hydroxytryptamine receptor subfamily. Serotonin has been implicated in a number of physiologic processes and pathologic conditions. Inactivation of this gene in mice results in behavior consistent with an increased anxiety and stress response. Mutation in the promoter of this gene has been associated with menstrual cycle-dependent periodic fevers. [provided by RefSeq， Jun 2012]。
