The CDC123 (cell division cycle protein 123)/CAMK1D (calcium/calmodulin-dependent protein kinase ID) locus on chromosome 10 contains common variants (MAF>.05) strongly associated with type 2 diabetes in Europeans (rs12779790, P = 1.2×10−10) [3], East Asians (rs10906115, P = 1.5×10−8) [4], and South Asians (rs11257622, P = 5.8×10−6) [5]. Here, CAMK1D is linked to type 2 diabetes mellitus.
