Hemophilia A and B are genetic disorders caused by missing or defective clotting proteins. Although hemophilia is passed down from parents to children, about 1/3 of cases found have no previous family history.

People with hemophilia bleed longer than other people. Bleeds can occur internally, into joints and muscles, or externally, from minor cuts, dental procedures, or injuries.

The main medication to treat hemophilia is a concentrated product called clotting factor or simply factor. Recombinant factor products, which are developed in a lab through the use of DNA technology, preclude the use of human-derived pools of donor-sourced plasma.
