rs7495174 is located in intron 1 of the OCA2 gene. The (A) allele (in dbSNP orientation) is associated with blue or green eye color in Caucasians. [PMID 17236130].
This SNP is 1 of 3 SNPs defining a haplotype that has been studied for association with eye color. The full details on the correspondence between the haplotype and eye color can be found on the OCA2 page.
