ABSTRACT

Background

Coronary artery disease (CAD) is a devastating illness and a leading cause of death worldwide, primarily caused by atherosclerosis resulting from a genetic‐environmental interaction. This study aimed to investigate the relationship between the ESR1 (rs9340799), OLR1 (rs3736234), LIPC (rs2070895), VDR (rs2228570), and CETP (rs708272) polymorphisms, lipid profile parameters, and CAD risk in a southeast Iranian population.

Methods

A total of 400 subjects (200 CAD patients with hyperlipidemia and 200 healthy controls) were enrolled in this case–control study. Five selected polymorphisms were genotyped using the polymerase chain reaction–restriction fragment length polymorphism (PCR‐RFLP) technique.

Results

For all single nucleotide polymorphisms (SNPs), the population under study was in the Hardy–Weinberg equilibrium. The T‐risk allele frequency of rs2228570 was associated with an increased risk of CAD. The TT and CT genotypes of rs2228570 had also been associated with the risk of CAD. Additionally, the TT genotype was associated with higher serum low‐density lipoprotein cholesterol (LDL‐c) and high‐density lipoprotein cholesterol (HDL‐c) levels. The GG genotype of the rs3736234 was associated with higher body mass index (BMI) and triglyceride (TG) levels, and the AA genotype of the rs708272 was associated with higher HDL‐c levels. Based on these findings, we propose that the VDR (rs2228570) polymorphism was associated with serum HDL‐c and LDL‐c levels and may serve as potential risk factors for CAD within the Iranian population. Moreover, rs3736234 and rs708272 influence the concentrations of TG and HDL‐c, respectively.

Conclusion

These findings provided insights into the complex interplay between genetic variations, cardiovascular risk, and lipid metabolism.
