Figure 1

The linkage disequilibrium (LD) structures of PARL (a) and PINK1 (b) in leprosy patients and healthy controls from the Yuxi Prefecture and pooled control samples. Black squares represented high LD as measured by r², gradually coloring down to white squares of low LD. The individual square showed the r² value for each SNP pair (r² value is multiplied by 100). The pooled control samples contained the reported Han Chinese without leprosy from Hunan Province (N = 984), Shanghai (N = 1526)²⁷, and the Yuxi control samples in this study (Yuxi).
