Abstract Background/purpose Data on the role of the −455G > A polymorphism of the gene encoding β fibrinogen subunit ( FGB ) and the Thr312Ala polymorphism of the gene for the α fibrinogen subunit ( FGA ) in childhood ischemic stroke are insufficient. Therefore the aim of the study was to evaluate a possible association between these two polymorphisms and arterial ischemic stroke. Methods The study group consisted of 85 children after ischemic stroke, 146 of their parents and 159 controls. Both polymorphisms were genotyped using the restriction fragment length polymorphism method. Two study designs were used: a case–control model and a family-based transmission-disequilibrium test. Statistica 7.1 and EpiInfo 6 softwares were used in all analyses. Results In the TDT test, a tendency to a higher transmission of the 312Ala allele of the FGA gene and the −455A allele of the FGB gene was observed, however, it was statistically non-significant. The frequencies of alleles and genotypes of both FGA and FGB genes polymorphisms did not differentiate children from both groups also in the case–control model. Additive or synergistic effects between FGA and FGB genes polymorphisms were not observed. Conclusion An analysis of the results obtained in this study and a critical review of previously published data indicate that examined gene polymorphisms are not related to ischemic stroke in children.
