Linkage disequilibrium analysis ofmiR-146aC > G,miR-149T > C,miR-196a2T > C, andmiR-499T > C SNPs. The number at the intersection of each pair of SNPs represent the pairwise D, D′, r2 and P values between two SNPs. Values of D’ > 0.75 and P < 0.0001 were considered to be strong pairwise linkage disequilibrium. SNP1: miR-499, SNP2: miR-196a2, SNP3: miR-146a, SNP4: miR-149. A: Uygur population; B: Kazak population; C: Southern Han population.
