What Causes Hemophilia?

Hemophilia is a rare inherited blood disorder. This genetic disease is caused by a defect in the genes that determine how the body makes blood clotting factors. Because these genes are on the X chromosome (men have XY women have XX), women can be carriers of the disease (if they have one defective X chromosome) whereas men with the defective gene will have hemophilia.
