Association between single nucleotide polymorphism rs9534275 and the risk of coronary artery disease and ischemic stroke.


ABSTRACT: The present study was to detect the association of single nucleotide polymorphism (SNP) in the breast susceptibility gene 2 (BRCA2) and the risk of coronary artery disease (CAD) and ischemic stroke (IS).Genotypes of the BRCA2 rs9534275 in 1822 unrelated subjects (CAD, 606; IS, 569; and healthy controls, 647) were determined by the polymerase chain reaction and restriction fragment length polymorphism and then confirmed by direct sequencing.The genotypic and allelic frequencies of rs9534275 were significantly different between the CAD, IS patients and controls (P = 0.033 and P = 0.027; respectively). The GG, GT/GG genotypes and G allele were associated with an increased risk of CAD and IS (CAD: P = 0.005 for GG vs. TT, P = 0.004 for GT/GG vs. TT, P = 0.005 for G vs. T; IS: P = 0.003 for GG vs. TT, P = 0.005 for GT/GG vs. TT; P = 0.002 for G vs. T). The GG, GT and GT/GG genotypes in the CAD, but not in healthy controls and IS patients, were associated with an increased serum total cholesterol (TC) and apolipoprotein B (ApoB) concentration.The present study shows that the G allele carriers of BRCA2 rs9534275 were associated with increased serum TC and ApoB levels in the CAD patients and increased risk of CAD and IS.Retrospectively registered.
