Based on the GWAS study, Protein C-ets-1, DNA-binding protein Ikaros, Ras guanyl-releasing protein 3, Solute carrier family 15 member 4, TNF-α-induced protein 3-interacting protein 1 (TNIP1), 7q11.23, 10q11.22, 11q23.3 and 16p11.2 were identified associating with SLE susceptibility in a Chinese Han population [5].
