Genotyping of 2 Cholesteryl Ester Transfer Protein Gene Variants Among Coronary Artery Disease Patients

Introduction: Coronary artery diseases (CAD) are still among the top causes of death in most populations. The polymorphisms of the cholesteryl ester transfer protein (CETP) gene can influence the risk of CAD through modulating cholesterol metabolism. In this regard, the current study aimed to determine the role of the 2 important CETP gene polymorphisms in CAD patients. Methods: To this end, DNA was extracted from the whole blood of 100 CAD patients and 100 healthy controls and then subjected to polymerase chain reaction-restriction fragment length polymorphism for the genotyping of rs5882 and rs708272 polymorphisms. Results: Based on the results, no meaningful association was found between rs5882 and rs708272 polymorphisms, neither separately nor in combination, and the risk of CAD. However, the risk of CAD significantly increased in male rs5882 polymorphism carriers (P = 0.01). Finally, no significant association was demonstrated between serum high-density lipoprotein levels and the genotypes or alleles of neither rs5882 nor rs708272 polymorphism. Conclusion: Despite the finding regarding the lack of an association between CAD and the studied polymorphisms of the CETP gene, the importance of those variants in CETP protein function and CAD pathogenesis warrants further investigation on larger populations.
