Left, before removal of SNPs located within known leprosy loci. Right, after removal of SNPs located within known leprosy loci. The dotted vertical line in the right panel shows the point where the statistics lift off from the expected null distribution (–log10 (P) of 3 to 4), which becomes the statistical threshold for our SNP selection (P < 5 × 10−4).
