Understanding von Willebrand Factor (VWF), Factor II, and Factor V Leiden Mutations: Risks, Management, and Medication Considerations
Genetic clotting disorders such as Factor V Leiden and Factor II (Prothrombin G20210A) mutations are common causes of inherited thrombophilia. These conditions increase the likelihood of developing dangerous blood clots. When both mutations are present, the risk is significantly elevated. Additionally, disorders involving von Willebrand Factor (VWF) can cause serious bleeding problems. Management of these conditions involves careful balance—preventing abnormal clotting while avoiding excessive bleeding, especially when anticoagulants are prescribed. Overview of Genetic Clotting and Bleeding Disorders Factor V Leiden Cytochrome P450 (CYP450) tests Factor V Leiden is a genetic mutation that makes Factor V resistant to breakdown by activated Protein C (APC), a key anticoagulant protein. As a result, clotting activity is prolonged, increasing the risk of venous thromboembolism (VTE). It is the most common hereditary cause of thrombophilia, particularly in in...
