Fig. 2From: Polymorphisms in the airway epithelium related genes CDHR3 and EMSY are associated with asthma susceptibilitythe Analysis of linkage disequilibrium of 20 tag-SNPs in CDHR3. Note: Each square represents the linkage disequilibrium of two corresponding SNPs, which is displayed as r2 × 100. The larger the darkness of the square, the larger the value of r2 × 100Back to article page
