Hemophilia | Overview

Hemophilia A is a genetic bleeding disorder caused by a mutation in the F8 gene that leads to  low levels of a protein called factor VIII. Factor VIII is necessary for blood clotting. Severe hemophilia A can cause prolonged or spontaneous bleeding, particularly in the muscles and joints, or internal organs. The current standard of care for hemophilia A is to control or prevent bleeding episodes through factor replacement therapy, given by regular intravenous (IV) infusions.
