The association of the prothrombin A19911G single-nucleotide polymorphism and the risk of venous thromboembolism: A systematic review and meta-analysis

Abstract

BackgroundThe study employed meta-analysis to provide a comprehensive synthesis of evidence regarding the association between the prothrombin A19911G polymorphism and the risk of venous thromboembolism (VTE).MethodThe databases were searched to identify studies investigating the association between the prothrombin A19911G polymorphism and the risk of VTE. Meta-analysis was conducted using Stata 14.0 software.ResultsA total of five literature studies were included, involving 14,001 participants. Meta-analysis demonstrated that prothrombin A19911G polymorphism increased the risk of VTE (G vs A: OR = 1.17, 95% CI = 1.11–1.22, p < .00001; GG + AG vs AA: OR = 1.22, 95% CI = 1.13–1.31, p < .00001; GG vs AG + AA: OR = 1.23, 95% CI = 1.14–1.33, p < .00001; AG vs AA: OR = 1.15, 95% CI = 1.06–1.25, p = .0006; GG vs AA: OR = 1.34, 95% CI = 1.22–1.48, p < .00001).ConclusionThe polymorphism of prothrombin A19911G enhances the susceptibility to VTE.
