HLA-C and psoriasis: In total we examined 30 AI SNPs, including four with established vitiligo-melanoma associations either as the joint lead risk SNP for both conditions (rs1126809 and rs6059655) or in strong linkage disequilibrium with known cutaneous melanoma risk SNPs (rs72928038 and rs251464)30 and one (rs9468925) that is associated with both psoriasis and vitiligo and falls in between HLA-C/HLA-B.60
