We found 11 genes in common between our hits and homologs associated with T2D, including the human homolog of COT1, SLC30A8, which encodes a zinc transporter in the secretory vesicles of pancreatic β cells and was found to be associated with T2D in 12 of 42 GWASs (Table S6). This evidence concerns the gene SLC30A8 and type 2 diabetes mellitus.
