There is a strong genetic predisposition to cardiovascular disease (CVD). Loss-of-function variants of the angiopoietin-like 3 (ANGPTL3) gene have been reported to be associated with several lipid-related CVD risk factors that include serum high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG) level, and total cholesterol (TC). We aimed to determine the association of two genetic variants, rs1748195 and rs11207997, of the ANGPTL3 locus and CVD risk in the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. The participants were 1002 individuals in the MASHAD cohort, with or without CVD, during the 6 years of follow-up. The subjects were categorized into two groups according to serum HDL concentration. DNA was extracted by the routine salting-out method, and genotyping of rs1748195 and rs11207997 variants of the ANGPTL3 gene was performed using the ARMS PCR method. Univariate and multivariate statistical analysis was used to assess the two gene variants’ association with incident CVD and baseline lipid profile. There was a significant relationship between rs1748195 GG genotype and CVD risk in the individuals with a normal serum HDL-C. There was a significant association between the CT genotype of the rs11207997 polymorphism and CVD risk in individuals with a low serum HDL-C. Furthermore, carriers of the GG genotype of the rs1748195 and CT genotype of rs11207997 variant of ANGPTL3 had a higher risk of developing CVD disease. We have shown that the 1748195(GG) and 11207997(CT) gene variants of the ANGPTL3 locus are associated with an increased risk of CVD in an Iranian population sample.
