The authors also examined SNPs associated with the identified DEGs T2D and metabolic traits and found 148 SNPs associated with islet expression of several genes including PCOLCE2. Six eQTL SNPs associated with islet expression of PCOLCE2 (rs6794287) have been linked to triglyceride or LDL cholesterol levels. The gene discussed is PCOLCE2; the disease is type 2 diabetes mellitus.
