Fig. 2.

Locations of the genotyped tag SNP sites in TYK2 in the International HapMap (upper) and iHap (lower) data. The horizontal bars in the middle indicate the genomic sequence of TYK2. Blue vertical bars indicate the positions of all SNP sites. A yellow rectangle represents the positions of a linkage disequilibrium block. A list and the locations of candidate tag SNPs are shown in the lower right position using Haploview 4.0 software. Red inverted triangles indicate the genotyped tag SNPs sites in this study, and their names are presented above each inverted triangle
