HLA-B and vitiligo: Our results on selected candidate genes in conferring oxidative stress and autoimmunity suggest that HLA-A*33:01, HLA-A*02:01,HLA-B*44:03, HLA-DRB1*07:01 and a few studied polymorphisms in IL4, CTLA4, SOD2, SOD3, GPX1, NALP1, MYG1, TNFA, TNFB, IFNG and IL10 genes are strongly associated with vitiligo susceptibility, whereas a few studied polymorphisms in PTPN22, MBL2, ACE, CAT, G6PD and SOD1 genes are not found to be significantly associated with Gujarat vitiligo patients.
