Comprehensive reanalysis of genome wide data of 33 biological candidate genes previously implicated in generalized vitiligo (ACE, AIRE, CAT, CD4, CLEC11A, COMT, CTLA4, C12orf10, DDR1, EDN1, ESR1, FAS, FBXO11, FOXD3, FOXP3, GSTM1, GSTT1, IL1RN, IL10, KITLG, MBL2, NFE2L2, PDGFRA-KIT, PTGS2, STAT4, TAP1-PSMB8, TGFBR2, TNF, TSLP, TXNDC5, UVRAG, VDR, and XBP1) has identified three candidate genes XBP1, FOXP3, and TSLP in association with vitiligo that are not shared by other autoimmune diseases (Chen et al., 2005; Birlea et al., 2010, 2011; Jin et al., 2010; Tang et al., 2013). The gene discussed is CD4; the disease is autoimmune disease.
