In a recent GWAS, the HLA-C gene was associated with type I psoriasis (p = 2.97E − 18 for rs1265181, p = 2.58E − 15 for rs12191877, p = 1.84E − 15 for rs4406273, and p = 1.10E − 07 for rs2395029), but not with type II psoriasis after application of the Bonferroni correction [11]. Here, HLA-C is linked to psoriasis.
