What does haemophilia result from?

Question

Quizplus · Accepted Answer

Haemophilia results from an inability to produce one of the factors in the clotting cascade. Specifically, haemophilia A results from a deficiency in clotting factor VIII, while haemophilia B results from a deficiency in clotting factor IX. This leads to a prolonged bleeding time and an increased risk of bleeding episodes, both internally and externally. Haemophilia is not caused by a deficiency of platelets, inadequate haemoglobin production, or vitamin B12 deficiency.
