Hemophilia is a rare, inherited bleeding disorder characterized by a partial or total deficiency of a clotting factor, leading to a tendency to bleed into various tissues in the body. In both these states, the lack is caused by a defective gene. Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot.
