HTR2A - 5-hydroxytryptamine receptor 2A Gene
Also Known as HTR2; 5-HT2A
Species: Homo sapiens
About HTR2A
This gene has 3 transcripts (splice variants), 222 orthologues, 8 paralogues and is associated with 5 phenotypes. Biased expression in brain (RPKM 11.8) and gall bladder (RPKM 0.8).
Summary
This gene encodes one of the receptors for serotonin, a neurotransmitter with many roles. Mutations in this gene are associated with susceptibility to schizophrenia and obsessive-compulsive disorder, and are also associated with response to the antidepressant citalopram in patients with major depressive disorder (MDD). MDD patients who also have a mutation in intron 2 of this gene show a significantly reduced response to citalopram as this antidepressant downregulates expression of this gene. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]
