VDR and type 2 diabetes mellitus: A similar pattern of association was seen where only five significant associations were reported for vitamin D synthesis-related genes (DHCR7 and CYP2R1) as compared to the vitamin D metabolism-related genes (CYP24A1, GC and VDR), where 30 significant associations were observed, and, in particular, 26 significant associations with T2D was seen for the VDR SNPs.
