This SNP, located in an intron of the GRIA3 gene (also known as AMPA3), has been linked in one study to increased thoughts of suicide in patients taking the anti-depressant drug citalopram. The increased risk is calculated to be 1.9x. If the individual is also carrying two rs2518224(C) alleles, i.e. is a rs2518224(C;C) homozygote, the odds ratio for having suicidal thoughts is increased to ~15x (CI: 3.7 - 60.6). [PMID 17898344]
