INTRODUCTION AND OBJECTIVE: Genetic susceptibility has a key role in the pathogenesis of coronary artery disease (CAD). KLF5 and KLF7 are transcriptional factors essential to cell development and differentiation. Their genetic variants have been associated with the risk of metabolic disorders. The present study aimed to evaluate the possible correlation of KLF5 (rs3812852) and KLF7 (rs2302870) single nucleotide polymorphisms (SNPs) with the risk of CAD for the first time in the world.
METHODS: The clinical trial study comprised 150 patients with CAD and 150 control subjects without CAD from the Iranian population. After blood sampling, deoxyribonucleic acid was extracted and genotyped using the Tetra Primer ARMS-PCR method and confirmed by Sanger sequencing.
RESULTS: The KLF7 A/C genotypes and C allele frequency were meaningfully higher in the control group compared to the CAD+ group (p<0.05). No obvious association has been observed between KLF5 variants and CAD risk. However, the distribution of the AG genotype of KLF5 was statistically lower in CAD+ patients with diabetes than in CAD+ patients without diabetes (p<0.05).
CONCLUSION: This study identified KLF7 SNP as a causative gene contributing to CAD, which presents novel insight into the molecular pathogenesis of the disease. It is, however, unlikely that KLF5 SNP has an essential role in the risk of CAD in the studied population.
