For example, SNPs of TNFAIP3 region associated with systemic lupus erythematosus, rheumatoid arthritis, and type1 diabetes are different from SNPs associated with psoriasis and celiac disease (Plenge et al. 2007; Thomson et al. 2007; Nair et al. 2009). The gene discussed is TNFAIP3; the disease is psoriasis.
