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

Background: The 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). Method: The 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. Results: A 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). Conclusion: The polymorphism of prothrombin A19911G enhances the susceptibility to VTE. [ABSTRACT FROM AUTHOR]
