3 Figure 2 Regional Plots for Evidence of cis-Association between SNPs and ERAP2 or RPS26 The most significant SNPs (the most significant SNP associated with ERAP2 in normal skin on the left panel; the most significant SNP associated with RPS26 in uninvolved skin on the right panel) are highlighted with a square. The other SNPs are drawn as circles and color coded according to the degree of linkage disequilibrium with the most significant SNP.
