|(C;T)||higher risk for RA; better response to paroxetine as treatment for depression|
Based on a study of 166 Caucasian patients being treated for depression with paroxetine, rs6314 heterozygotes were associated with better response. There was a significantly higher frequency of heterozygotes in the remitter and response groups in comparison to the non-remitter (odds ratio 7.50, p=0.002) and non-response groups (odds ratio 5.25, p=0.01).10.1038/sj.tpj.6500491
- rs6314 is part of a 4-SNP haplotype in the serotonin 2A receptor gene HTR2A that has been associated with rheumatoid arthritis in a study of 1800 European patients. The risk allele is rs6314(C). The overall risk for the haplotype CTCC of SNPs rs6311-rs1328674-rs6313-rs6314 is 1.68 (CI: 1.20 - 2.34, p = 0.02). [PMID 18006541]
Note: the orientation of rs1328674 in dbSNP is opposite that cited by this publication; therefore, with respect to dbSNP, the haplotype of risk as cited above is CACC rather than CTCC.

- "Haplotype association analysis suggests that the haplotype CCGCA (at SNPs rs3125, rs6314, rs1923886, rs2224721 and rs2770296) is protective against bipolar disorder (P = 0.021, odds ratio 0.63) and the rarer haplotype CCACG confers risk to the disorder (P = 0.0065, odds ratio 3.08)."
