Association of the ANGPTL3 gene polymorphisms and haplotypes with cardiovascular diseases in Birjand longitudinal aging study (BLAS)

Abstract

SubjectCardiovascular 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).MethodTotally, 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.ResultsUnivariate 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.ConclusionWe 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.
