Association of APOA5 -1131T>C polymorphism and serum lipid levels in patients with type 2 diabetes

Significant abnormalities in lipid metabolism are frequently present in patients with type 2 diabetes mellitus (T2DM). Hypertriglyceridemia, a highly proatherogenic state, is associated with increased risk of coronary artery disease. Genetic polymorphism APOA5 -1131T>C has been recognized as a significant contributor to hypertriglyceridemia in both healthy and diabetic populations. The aim of the study was to investigate the association of APOA5 -1131T>C polymorphism with the serum levels of triglycerides, total cholesterol, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol in patients with T2DM. In total, 234 DNA samples from patients with T2DM were genotyped using the PCR-RFLP method. Serum lipid levels were measured using standard laboratory methods. Obtained APOA5 -1131T>C genotype frequencies were 89% (T/T) and 11% (T/C+C/C). There was no significant association between APOA5 -1131T>C genotypes and triglyceride levels (1.90 mM [1.32-2.74] vs. 1.78 mM [1.54-3.05] for T/T vs. T/C+C/C genotype ; p=0.553), HDL cholesterol levels (1.30 mM [1.10-1.40] vs. 1.30 mM [1.05-1.40] for T/T vs. T/C+C/C ; p=0.534), and LDL cholesterol levels (3.1 mM [2.3-3.8] vs. 3.0 mM [2.2-3.5] for T/T vs. T/C+C/C ; p=0.313). Our results suggest that hypertriglyceridemia in patients with T2DM is not likely to be associated with the APOA5 -1131T>C polymorphism.
