HLA-C and psoriasis: In detail, minor alleles of rs1062470, rs2894207 and rs10484554 strongly increased the risk of psoriasis (OR = 2.17, 95% CI 1.80–2.63, p < 0.0001; OR = 2.33, 95% CI 1.92–2.82, p < 0.0001 and OR = 2.68, 95% CI 2.19–3.28, p < 0.0001, respectively), and these results were slightly lower than those for HLA-C*06:02 obtained for the same patients and controls in our earlier study (OR = 3.58, 95% CI 2.82–4.54, p < 0.0001) (Wiśniewski et al. 2018).
