The region on Chr C2 near SNPs 5 and 6, contained four known genes (TRA2B, CHCHD4, IGF2BP2 and SENP2) but none of these genes contained disease-associated protein-coding changes, despite TRA2B and IGF2BP2 having association with type 2 diabetes in other species [39]. Here, SENP2 is linked to type 2 diabetes mellitus.
