There were 14 genes (JAZF1, IGF2BP2, NRXN3, ADAMTS9-AS2, GIPR, FCHSD2, HHEX, EXOC6, KLF14, ARAP1, GNPDA2, GP2, C2CD4A and C2CD4B) that were associated with either BMI or T2D in previous studies but not with both that were detected as pleiotropic loci in this analysis. Here, GP2 is linked to type 2 diabetes mellitus.
