rs4570625, also known as G-703T, is a SNP in the tryptophan hydroxylase 2 TPH2 gene. This SNP has been linked to several psychiatric and/or behavioural phenomena, including:
- [PMID 16146581] rs4570625 and rs4565946 linked to the pathogenesis of early-onset obsessive compulsive disorder
- [PMID 19052197] rs4570625(G;G) homozygosity was a significant predictor of clinical placebo response, being associated with greater improvement in anxiety symptoms.
