In genetics, rs7997012 is a gene variation—a single nucleotide polymorphism (SNP)—in intron 2 of the human HTR2A gene that codes for the 5-HT2A receptor. The SNP varies between adenine (A) and guanine (G) DNA bases with the G-allele being most frequent. A research study found it to be related to antidepressant treatment.〔 Comments: * * 〕 The research group reported that a polymorphism (rs1954787) on another gene, the GRIK4, has also shown a treatment-response-association in this kind of treatment. In a Japanese study rs7997012 was not associated with neither major depressive disorder nor bipolar disorder. Rs6311, rs6313 and His452Tyr (rs6314) are other SNPs in the HTR2A gene. There are many more, even in intron 2 alone. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Rs7997012」の詳細全文を読む スポンサード リンク
