LP185938-0 HTR2A gene.c.1354C>T
Antidepressant and antipsychotic medication selection may be determined based on a patient's genotype for various polymorphisms within the HTR2A and HTR2C genes, which encode the serotonin (5-hydroxytryptamine) receptors HTR2A and HTR2C. PMID: 15121641 Variants in HTR2A, for example c.102T>C and c.-1438G>A, have been found to affect response to selective serotonin reuptake inhibitors (SSRI) and risk for adverse drug reactions as well as response to the antipsychotic drugs clozapine and aripiprazole. PMID: 14514498, PMID: 10821369 Patients treated with antipsychotics and having significant weight gain have been positively correlated with a polymorphism in the promoter region of HTR2C, c.759C>T, where those with the -759T variant allele showed significantly less weight gain than those without this allele. PMID: 12668355

LP40502-4 HTR2A gene
The HTR2A gene is located on chromosome 13 at position q14-q21 and encodes one of the receptors for serotonin, a neurotransmitter with many roles.[HGNC Gene ID:5293] 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] [NCBI Gene ID: 3356]
