Interestingly, at least 12 genes including SLC2A2, G6PC2, SLC30A8, PCSK1 and RAPGEF4, also overlap with previously implicated genes from genome wide association studies (GWAS) for type 2 diabetes mellitus and blood glucose loci (Supplementary Table 3). The gene discussed is PCSK1; the disease is type 2 diabetes mellitus.
