Congenital afibrinogenemia
Definition
Congenital afibrinogenemia is a rare, inherited blood disorder in which the blood does not clot normally. It occurs when you are missing or have a problem with a protein called fibrinogen, which is needed for the blood to clot.
Causes
This rare disease is caused by an abnormal gene that must be passed down from both parents. There may be either a lack of fibrinogen or a defect in the functioning of available fibrinogen. This condition can occur in both sexes. The main risk factor is a family history of bleeding disorders.
