TNIP1 and psoriasis: SNPs in the TNFAIP3 gene, but also in other immune-regulatory genes including HLA-C, TNIP1/ABIN-1 and IL-23A (Nair et al., 2009; Strange et al., 2010; Johnson-Huang et al., 2012) have been associated to psoriasis and polymorphisms in the TNFAIP3 gene correlate to responsiveness to TNFα blockers in psoriasis patients (Tejasvi et al., 2012).
