Key result
The GG genotype of the ANGPTL3 rs1748195 polymorphism was associated with a significantly increased risk of cardiovascular disease (OR 2.43) compared to the reference genotype.
Why the study?
Newly identified single nucleotide polymorphisms of ANGPTL3 influence lipid concentrations and coronary artery disease risk, but their association with incident CVD in an elderly population required evaluation.
Do ANGPTL3 gene polymorphisms and haplotypes associate with cardiovascular diseases in an elderly population?

Specific ANGPTL3 gene polymorphisms (rs1748195 and rs11207997) and haplotypes are significantly associated with the risk of cardiovascular diseases and lipid profile variations in an elderly Iranian population.

Subject Cardiovascular disease is now well established as an interaction between genetic and environmental components. Newly identified single nucleotide polymorphisms of angiopoietin-like 3 (ANGPTL3) influence lipid concentrations and risk of coronary artery disease. The current study aimed to determine the association between ANGPTL3 gene variants with incident CVDs in elderly population of the Birjand longitudinal aging study (BLAS). Method Totally, 360 individuals were recruited in baseline of BLAS including 128 patients with CVD and 153 control subjects. DNA extraction of samples and genotyping were performed by Tetra-ARMS PCR (amplification refractory mutation system polymerase chain reaction). The association between three polymorphisms of ANGPTL3 gene (rs1748195, rs11207997, and rs10789117 variants) with CVD and its risk factors were evaluated using multivariate analysis. Results Univariate and multiple analyses showed that individuals carrying the GG genotype of rs1748195 and those carrying the TT genotype of rs11207997 directly increased the risk of CVD. CC genotype of rs1748195 and rs11207997 polymorphisms had a significant negative relationship with the disease. In addition, the findings of this study indicate a significant difference in LDL, HDL, cholesterol levels between different genotypes of the rs1748195 and rs10789117 in the healthy group. Individuals with haplotypes CAC, CCC and CCT showed a significant positive relationship with CVD, CVA, AMI and CHD. As well as haplotype was associated with a 1.7-fold increase in risk of CVA, AMI, and CHD. Conclusion We found that polymorphism of ANGPTL3 gene might support to identify individuals with a cardiometabolic and genetic disorders susceptibility. Three haplotypes CAC, CCC and CCT associated with CVD, CVA, AMI and CHD were reported.

Poursalehi et al. (2022) conducted a cohort in Cardiovascular disease (n=360). ANGPTL3 gene polymorphisms (rs1748195 and rs11207997) vs. Non-carriers / reference genotypes was evaluated on Risk of cardiovascular disease (CVD) associated with the rs1748195 GG genotype (OR 2.43, 95% CI 1.25-4.71, p=0.008). The GG genotype of the ANGPTL3 rs1748195 polymorphism was associated with a significantly increased risk of cardiovascular disease (OR 2.43) compared to the reference genotype.
