In fact, HLA-DRB1, HLA-DQA1 (14), and HLA-A (15) have been documented to be associated with vitiligo in the Caucasian population via regulation of HLA gene expression, and our team has reported the association of three novel HLA alleles (HLA-DQB1 *02:02, HLA-DQA1*02:01 and HLA-DPB1*17:01) (16) with vitiligo based on the HAN-MHC reference panel (17). Here, HLA-C is linked to vitiligo.
