Evaluation of the association between FGBrs1800790 and plasma fibrinogen levels

Fibrinogen، coagulation factor 1، is a soluble plasma glycoprotein which converts thrombin to fibrin fibers in the coagulation cascade. Various polymorphisms located on beta chain gene، FGB، have been studied. The promoter – G455A (rs1800790) polymorphism had been shown to be significantly associated with fibrinogen plasma levels. In this study، the frequency of rs1800790 polymorphism has been assessed and the correlation was evaluated between this variant and fibrinogen plasma levels. Whole blood samples were collected for DNA isolation. To perform rs1800790 genotyping، the region encompassing the HaeIII restriction site was amplified using specific primers. The plasma levels of fibrinogen were measured and the obtained data were analyzed by SPSS software. The levels of plasma fibrinogen has shown a significant correlation with FGBrs1800790 genotype (p-value = 0. 021; CI = 0. 347 - 3. 253). Minor allele frequency was estimated to be 0. 28 which was consistent with the predicted value. The significant correlation between fibrinogen and FGBrs1800790 genotype emphasizes the importance of this variant in the modulation of fibrinogen plasma concentrations. Since FGBrs1800790 contributes to the gene expression and environmental risk factors، it is important to be noticed in the cardiovascular disease.
