ANGPTL8 and type 2 diabetes mellitus: The frequency of ANGPTL8 C allele (wild allele) was significantly higher in T2DM + CVD patients than in T2DM patients (96.3% vs. 86.7% p = 0.03) and associated with 2.8-times increased risk of CVD in T2DM patients (95% CI 1.13–6.97), while the variant T allele was significantly higher in T2DM patients without CVD than in T2DM + CVD patients (13.3% vs. 3.7%, respectively).
