For green versus blue eye color rs12913832 in OCA2/HERC2 has a score of 51.5 and an estimated allelic OR of 8.43 . The SNP rs1667394 in this same region has an estimated OR of (4.85–10.06).10.1371/journal.pgen.1000993
rs12913832 is also part of a haplotype spanning 166kB on chromosome 15, defined by 13 SNPs listed below, that is found in 97% of all Caucasians with blue eyes. In this haplotype, variations in rs1129038 and rs12913832 are relatively common in Caucasians though rare among other racial groups.[PMID 18172690]
