Three of these SNPs were located in six genes (ARF5, PAX4, SND1, GCC1, C2CD4A, C2CD4B) that were identified to be associated with T2D in only East Asian populations, while HHEX was common to both East Asian and Europeans, and two genes (THADA, IDE) were specific to the Europeans. The gene discussed is GCC1; the disease is type 2 diabetes mellitus.
