▶Neuroplasticity and second messenger pathways in antidepressant efficacy: pharmacogenetic results from a prospective trial investigating treatment resistanceAssociationN=2,066Chiara Fabbri et al.(2017)· European Archives of Psychiatry and Clinical Neuroscience
A prospective pharmacogenetic study of 220 treatment-resistant depression (TRD) patients examined 50 tag SNPs in 14 neuroplasticity and second messenger pathway genes for association with antidepressant response. Key findings included replication of ZNF804A rs7603001 with venlafaxine response (OR=2.51), CREB1 rs2254137 with remission, CHL1 rs2133402 with lower TRD risk, and MAPK1 rs6928 with all phenotypes (p=0.0006 after Bonferroni). Pathway analysis in STAR*D (n=1846) identified protein processing in the endoplasmic reticulum pathway as a potential mechanism of MAPK1 involvement.
About HTR2A
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]
