Fig. 1.
Single nucleotide polymorphism (SNP) linkage disequilibrium structure for the nominally significant SNPs in the insulin receptor substrate 2 (IRS2) gene. SNPs are indicated by their physical order within or nearby the gene on the x-axis. The degree of correlation (ρ) between SNP pairs is indicated by the intensity of shading in the small squares of the central figure with perfect correlation between identical SNPs along the diagonal.
