IL10 and psoriasis: Three single‐nucleotide polymorphisms (SNPs) at ‐592A/C (rs1800872), ‐819C/T (rs3021097), and ‐1082A/G (rs1800896) in the IL‐10 promoter region have recently been evaluated in a number of genetic association studies regarding their relationship with psoriasis susceptibility, but the findings of these studies are contradictory.
