At the T2D-associated CDC123/CAMK1D locus [1,3], the islet cis-eQTL for CAMK1D (calcium/calmodulin-dependent protein kinase ID; exon permuted p = 2.0x10-4, q = 0.011, ß = 0.61) endorsed the designation of CAMK1D as the likely effector emanating from previous studies conducted in other tissues [18,35]. This evidence concerns the gene CDC123 and type 2 diabetes mellitus.
