Research Abstract |
Venous thromboembolism is a multifactorial disease resulting from a complex interaction between circumstantial and genetic factors. In this study, we investigated possible causative gene defects in a large Japanese family with inherited thrombophilia, and found a novel missense mutation in the prothrombin gene resulting in a variant prothrombin. The mutation located at one of the antithrombin (AT) binding sites of thrombin molecule. We prepared wild-type and mutant recombinant prothrombins, and compared by prothrombin activation, AT-binding, and thrombin generation assays. In thrombin-antithrombin complex (TAT) formation, the mutant thrombin was impareded to form TAT. In thrombin generation assay of reconstituted prothrombin-deficient plasma with recombinant prothrombins, the mutant showed a decreased peak thrombin and an increased endogenous thrombin potential. We identified a novel F2 mutation leading to the mutant AT-resistant thrombin, which could be a cause of the inherited thrombophilia in this family.
