IL23A and psoriasis: Figure 8 reveals that IL23A correlates with several genes unrelated to IL17A, a finding confirmed by meta-analyses across all psoriasis RNA-Seq datasets. Included in the analysis were genes identified by GWAS to be linked to psoriasis. Of these genes, CARM1, KRT14, KRT37, TNFAIP3, UBE2L3 are elevated in psoriasis plaques compared to control healthy skin (Table 1). Thus, IL23A appears to be linked to other genes putatively involved in the pathophysiology of psoriasis that are unrelated to IL17A.
