%X <B>OBJECTIVE: </B>The prothrombin (PT) G20210A mutation is one of the most prevalent genetic variations associated with an increased susceptibility to the first episode of venous thromboembolism (VTE). However, it remains uncertain whether this inherited thrombophilic abnormality also poses a risk for recurrent VTE. This meta-analysis aimed to assess the relation of PT G20210A mutation to the risk of recurrent VTE.<BR><B>METHODS: </B>PubMed and Scopus were systematically searched for pertinent prospective studies. Relative risks (RR) and 95% confidence intervals (CI) were used to test the association. Sixteen studies, with 16,174 participants, were included.<BR><B>RESULTS: </B>Carriers of the G20210 A mutation were at increased risk of recurrent VTE (RR = 1.60, 95% CI = 1.20-2.14) compared to noncarriers; the increased risk was observed in heterozygotes (GA versus GG) (RR = 1.79, 95% CI = 1.24-2.57), but not in GA/AA mutation.<BR><B>CONCLUSIONS: </B>This association was found to be significant in the long term (≥5 years of follow-up), but not in the short term (<5 years of follow-up).
