We show that three independent SNPs in the TNFAIP3 region (rs13192841, rs2230926 and rs6922466) are associated with systemic lupus erythematosus (SLE) among individuals of European ancestry.

These findings extend our knowledge of susceptibility locus sharing across different autoimmune diseases, and provide convincing evidence that the RA/SLE locus 6q23/TNFAIP3 is a newly identified T1D locus.
TNFAIP3, an RA candidate gene, flanks this region, and polymorphisms in both the TNFAIP3 gene and the intergenic region are associated with systemic lupus erythematosus.
In the paper by Dieguez-Gonzalez and colleagues in the present issue of Arthritis Research & Therapy, the results of a detailed genetic investigation of the recently identified rheumatoid arthritis and systemic lupus erythematosus susceptibility region at 6q23 containing the TNFAIP3 gene are reported.
There are two nonsynonymous coding polymorphisms in the deubiquitinating (DUB) domain of TNFAIP3: F127C, which is in high-linkage disequilibrium with reported SLE-risk variants, and A125V, which has not been previously studied.
TNFAIP3 interacting protein 1, TNIP1 (ABIN-1) is involved in inhibition of nuclear factor-κB (NF-κB) activation by interacting with TNF alpha-induced protein 3, A20 (TNFAIP3), an established susceptibility gene to systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA).
Our findings suggest that SNP rs2230926 in the TNFAIP3 might be a common genetic factor for SLE within different populations in terms of Chinese Han and European population.
The replication analysis indicates that TNFAIP3, ETS1 and TNIP1 are probably common susceptibility genes for SLE in Chinese populations, and they may contribute to the pathogenesis of multiple SLE subphenotypes.
We selected and identified three SNPs of BANK1 associated with SLE (rs17266594, P = 1.949e-10; OR = 1.380; 95% CI: 1.250-1.525; rs10516487, P = 2.642e-13; OR = 1.317; 95% CI: 1.223-1.417; rs3733197, P = 3.452e-06; OR = 1.193; 95% CI: 1.107-1.286); one SNP of TNFAIP3 associated with SLE (rs2230926, P = 1.502e-12; OR = 1.826; 95% CI: 1.545-2.157).
