SzGene Meta-analysis

In genetics rs6311 is a gene variation—a single nucleotide polymorphism (SNP)—in the human HTR2A gene that codes for the 5-HT2A receptor. 5-HT2A is neuroreceptor, and several scientific studies have investigated the effect of the genetic variation on personality, e.g., personality traits measured with the Temperament and Character Inventory[1][2][3][4] or with a psychological task measuring impulsive behavior.[5] The SNP has also been investigated in rheumatology studies.[6][7]

Some research studies may refer to this gene variation as a C/T SNP,[2] while others refer to it as a G/A polymorphism in the promoter region, thus writing it as, e.g., −1438 G/A or 1438G>A.[8][9][10]

As of 2008, meta-analysis of research studies indicates that people with the A-allele may have slightly elevated risk of schizophrenia.[11]

rs6313, rs6314, and rs7997012 are other investigated SNPs in the HTR2A gene.
