CORRECTION:
Hemophilia is a bleeding disorder that slows the blood clotting process. People with this condition often experience prolonged bleeding or oozing following an injury, surgery. In severe cases of hemophilia, heavy bleeding occurs after minor trauma or even in the absence of injury. Serious complications can result from bleeding into the joints, muscles, brain, or other internal organs. Milder forms of hemophilia do not involve spontaneous bleeding, and the condition may only become apparent when abnormal bleeding occurs following surgery or a serious injury.
The big types of this condition are hemophilia A and hemophilia B. Although the two types have very similar signs and symptoms, they are caused by mutations in different genes. People with an unusual form of hemophilia B, known as hemophilia B Leyden, experience episodes of alot of bleeding in childhood, but have few bleeding problems after puberty. Another form of hemophilia, is not caused by inherited gene mutations. This rare condition is characterized by abnormal bleeding into the skin, muscles, or other soft tissues, usually beginning in adulthood.
