rs1667394 increases susceptibility to Blond rather than brown hair 4.94 times for carriers of the A allele [PMID 17952075]
rs1667394 increases susceptibility to Blue rather than brown eyes 29.43 times for carriers of the A allele [PMID 17952075]
rs1667394 increases susceptibility to Blue rather than green eyes 6.74 times for carriers of the A allele [PMID 17952075]
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
