Hemophilia is an X-linked congenital bleeding disorder caused by deficiency of coagulation factor VIII (in hemophilia A) or factor IX (in hemophilia B).

The deficiency is the result of mutations of the respective clotting factor genes.

Hemophilia is rare, with only about 1 instance in every 10,000 births (or 1 in 5,000 male births) for hemophilia A and 1 in 50,000 births for hemophilia B.

According to the World Federation of Hemophilia, 400 000 people worldwide & 5,307 people in Egypt are suffering from hemophilia.

Hemophilia A is more common than hemophilia B, representing 80-85 % of the total hemophilia population.
