Genetics
The 5-HT1A receptor is coded by the HTR1A gene. There are several human polymorphisms associated with this gene. A 2007 review listed 27 single nucleotide polymorphisms (SNP). The most investigated SNPs are C-1019G (rs6295), C-1018G, Ile28Val (rs1799921), Arg219Leu (rs1800044), and Gly22Ser (rs1799920). Some of the other SNPs are Pro16Leu, Gly272Asp, and the synonymous polymorphism G294A (rs6294). These gene variants have been studied in relation to psychiatric disorders with no definitive results.
