The positive vitiligo SNPs rs4807000 and rs6510827 are in the strong linkage disequilibrium (LD) region (r2 = 0.99) of 19p13.3 (Supplementary Figure 1), separately in 140 bp upstream and intronic region of TICAM1. According to Haploreg v4.1, these two SNPs are in the area of enhancer histone H3K4mel in primary melanocyte cells and primary keratinocyte cells. This evidence concerns the gene TICAM1 and vitiligo.
