What is the most common hypercoagulable state related to Factor V?

• A. Factor V deficiency
• B. Mutated Factor V resistant to Protein C and Protein S cleavage
• C. Increased platelet production
• D. Hyperhomocysteinemia

Answer: (B)

The most common hypercoagulable state related to Factor V is characterized by a mutation in Factor V that leads to resistance to the anticoagulant effects of Protein C and Protein S. This specific genetic mutation, known as Factor V Leiden, results in an alteration of the Factor V protein, making it less susceptible to degradation by activated Protein C. Consequently, this leads to prolonged clotting and an increased risk of thromboembolic events, making it a significant cause of venous thrombosis. Factor V deficiency, while a condition associated with bleeding, does not contribute to a hypercoagulable state. Rather, it leads to an increased risk of bleeding due to inadequate clot formation. Increased platelet production might suggest a hypercoagulable state but does not specifically relate to Factor V or its functions. Hyperhomocysteinemia is another condition that can contribute to thrombosis, but it is not directly related to Factor V alterations. Thus, the mutation of Factor V that confers resistance to Protein C and Protein S is the most relevant hypercoagulable state in this context.
