Abstract: © 2020, University of Kragujevac, Faculty of Science. All rights reserved. Thrombophilia is a condition of enhanced functionality of the haemostatic system with an increased tendency for thrombosis, and it can be a congenital, acquired, or complex defect. Pregnancy can be the cause of acquired transitory thrombophilia, which may lead to complications if inherited thrombophilia is also present. The aim of this study was to determine the genetic structure of the population based on the frequency of the gene variants factor V Leiden G1691A, factor II G20210A, methylenetetrahydrofolate reductase C677T, and plasminogen activator inhibitor-1 4G/5G, as well as to investigate the predictive value of these gene variants in repeated miscarriages. The study included 87 female patients from Central Serbia with an average age of 32.7±4.5 years with inherited thrombophilia and previous miscarriages, with or without intrauterine foetal death. The exclusion criteria included the existence of gynaecological and infectious aetiology and the deficit of factors important for the coagulation process. The resulting genotypes were in Hardy-Weinberg equilibrium. The frequency of genotypes with mutated alleles was significantly higher in this group of patients than in the control group for all variants except factor II G20210A. The most commonly mutated alleles were the plasminogen activator inhibitor-1 4G allele (0.61) and methylenetetrahydrofolate reductase T allele (0.47). Double mutation of plasminogen activator inhibitor-1 4G/5G and methylenetetrahydrofolate reductase C677T was dominant in patients with recurrent pregnancy loss (46.15%). The presence of a combination of genetic variants of the plasminogen activator inhibitor-1 4G/5G and methylenetetrahydrofolate reductase C677T is a significant predictor of spontaneous abortions in women with inherited thrombophilia in Central Serbia.
