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 a 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[update] , 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.
