Transethnic meta-analysis of the above African ancestry studies with a large GWAS of European ancestry individuals (the DIAGRAM meta-analysis of type 2 diabetes (T2D) based on the GoT2D integrated haplotypes)8 revealed multiple genome-wide significant loci as expected, including TCF7L2, KCNQ1, FTO, IDE, IGF2BP2, CDKAL1, and SLC30A8. However, they are all known loci, and none is a novel locus for T2D. Here, IGF2BP2 is linked to type 2 diabetes mellitus.
