The hemophilia gene is passed down from a parent to a child.Ībout one third of new cases are caused by a new mutation of the gene in the mother or the child. It cannot be caught or transmitted in any other way. Hemophilia is a genetic disorder, which is typically inherited. The most severe forms of these deficiencies are rarer than hemophilia A and B. Yes, several other factor deficiencies that also cause abnormal bleeding include deficiencies in factors I, II, V, VII, X, XI, XIII and von Willebrand factor. Are there other types of bleeding disorders? The only difference between these two types is that hemophilia A is about five times more common than hemophilia B. Hemophilia A-sometimes called classical hemophilia-, is caused by a deficiency of factor VIII, and hemophilia B-sometimes called Christmas disease-is caused by a deficiency of factor IX. What is the difference between hemophilia A and hemophilia B? The major problem for people with hemophilia is internal bleeding, mostly into muscles and joints. Clotting just takes longer how much longer depends on the severity of the disorder. Minor cuts and injuries will not cause them to bleed to death. People with hemophilia do not bleed faster than other people. People with hemophilia have either a low level or absence of one of these clotting factors in their blood.
