Ied at least one particular polymorphic allele (homozygote or heterozygote for the minor allele, GT TT) have been much less susceptible to psoriasis than these homozygous for the big allele (p = 0.002; adjusted OR = 0.594; 95 CI, 0.249.823). Even so, no important association involving psoriasis and rs2231137 was detected. These final results indicate a protective influence of ABCG2 polymorphisms on psoriasis.Genes 2021, 12,4 ofTable 2.

Interaction of ABCG2 Gene Polymorphisms with Clinical Qualities among Individuals with Psoriasis Since a genetic predisposition to psoriasis was noted, we further analyzed the 3-Chloro-5-hydroxybenzoic acid Biological Activity effect of ABCG2 gene polymorphisms on clinical traits in individuals with psoriasis (Tables three and 4). A significant association of rs2231142 variants (GG vs. GT TT) with hyperuricemia (p = 0.026; OR = 1.608, 95 CI: 1.057.447) was observed in psoriasis individuals. Even so, such association of rs2231142 variants was not demonstrated with age of onset, family members history of psoriasis, baseline PASI score, or psoriatic arthritis.Table 3.
