Objective:
To evaluate the correlation between prothrombin gene G20210A mutation and deep vein thrombosis after total joint replacement through detecting distribution frequency of single nucleotide polymorphism of the gene in patients undergoing total joint replacement.
Method:
PCR and direct sequencing of DNA are used to analyze the frequency of prothrombin gene G20210A mutation in 55 patients undergoing total joint replacement, and the relationship between the mutation and deep vein thrombosis after total joint replacement is evaluated.
Result:
Morbidity of prothrombin gene G20210A mutation in 55 patients is 0, both in either DVT group (27 patients) or non-DVT group (28 patients). There is no significant difference between the two groups (P>0.05).
Conclusion:
Mutation of prothrombin gene G20210A in Chinese patients is rare, and there is no correlation between the genetic mutation and deep vein thrombosis after total joint replacement.
