Most psoriasis susceptibility genes were identified in cohorts of mixed clinical phenotypes and the exploration of genes in clinical subtypes is scarce. IL-22 has an established role in host defense and in psoriasis skin pathology, reflecting the delicate balance between control of infection and immunopathology. In a case-control study, we compared the genetic association to IL22 in psoriasis onset in patients between 0-9 (n=207), 10-20 (n=394), and 21-40 (n=468) years with healthy controls (n=1,529). Logistic regression analysis revealed association to regulatory elements in the IL22 promoter confined to onset of psoriasis before puberty (odds ratio=1.45, P<0.0007). The associated variants contain putative bin... More
