For example, genetic variants at some genes (ADAMTS9, BCL11A, DCD, CENTD2, CHCHD2P9, DUSP9, FTO, JAZF1, PPARG, etc.) associated with T2D only in the GWAS of European populations, while genetic variants at some others genes (ANK1, CMIP, CR2, GCC1, GLIS3, HUNK, etc.)associated with T2D only in the GWAS of East Asian populations [40]. The gene discussed is ADAMTS9; the disease is type 2 diabetes mellitus.
