Hemophilia: Classical Hemophilia
built 257 days ago
Hemophilia is a rare genetic blood clotting disorder that primarily affects males. People living with hemophilia do not have enough of, or are missing, one of the blood clotting proteins naturally found in blood. Two of the most common forms of hemophilia are A and B. In persons with hemophilia A (... called classical hemophilia), clotting Factor VIII is not present in sufficient amounts or is absent. In persons with hemophilia B (also called Christmas disease), clotting Factor IX is not present in sufficient amounts or is absent. People with hemophilia do not bleed more profusely or bleed faster than normal; they bleed for a longer period of time.
Hemophilia A was the first recognized form of hemophilia. Hemophilia A is ... known as Factor VIII Deficiency and Classical Hemophilia. Patients with Hemophilia A do not have enough blood-clotting protein known as Factor VIII.
Hemophilia A or “classical hemophilia” is the most common type of hemophilia, making up about 80% of cases. It is caused by a deficiency of a specific clotting factor known as factor VIII (FVIII). An insufficient amount of clotting factor IX results in Hemophilia B, which accounts for most of the remaining 20% of hemophilia cases.
