Figure 1.
The co-regulation of pleiotropic genes associated with T1D and T2D is non-random. (a) A plot showing the number of unique and shared SNPs (imputed and genotyped) associated with the development of T1D and T2D identified from genome-wide association studies. (b) A normal distribution plot for randomly sampled SNPs (bootstrapping; n = 10,000) validates the significance of overlaps seen in (a). (c) The numbers of unique and shared genes modulated by T1D and T2D regulatory SNPs. (d) A normal distribution plot for randomly sampled genes (bootstrapping; n = 10,000) validates the significance of overlaps seen in (c). eGene—a gene whose transcript levels is associated with an eQTL, eQTL—SNPs associated with transcript levels of genes. Red lines in (b) and (d) illustrates the fitted normal distribution lines.
