INS and diabetes mellitus: In the overlap, 32 out of 317 (10.7%) reported diabetes SNPs were found to match directly or through a proxy with the identified cis-mQTL-SNPs, consisting of SNPs associated with type 1 diabetes (n = 12), type 2 diabetes (n = 12), fasting-plasma glucose (n = 4; 1 SNP overlapping with type 2 diabetes), 2 hour glucose challenge (n = 1), insulin response (n = 2) and proinsulin (n = 2) (Figure 6A–H; Table S14).
