CACNA1D and type 2 diabetes mellitus: Some known T2D genes were among the DEGs of the two pancreatic datasets (e.g., Solute Carrier Family 2 Member 2 (SLC2A2), Calcium Voltage-Gated Channel Subunit Alpha1 D (CACNA1D), which are known to play an essential role in T2D8, and 3-Hydroxy-3-Methylglutaryl-CoA Reductase (HMGCR), which is involved in cholesterol biosynthesis) but no common DEGs were observed across all the five datasets.
