5-HT2A: Products

5-HT2A encodes one of the receptors for serotonin, a neurotransmitter with many roles. Mutations in 5-HT2A 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 5-HT2A show a significantly reduced response to citalopram as this antidepressant downregulates expression of this gene.
