Definition of Congenital afibrinogenemia
Congenital afibrinogenemia is a rare, inherited blood disorder in which the blood does not normally. It occurs when there is a lack (deficiency) of a protein called fibrinogen, which is needed for the blood to clot.
Causes, incidence, and risk factors
This rare disease is caused by an abnormal gene that must be passed down from both parents. It causes a severe lack of fibrinogen. (Dysfibrinogenemia, in which there is a defect in fibrinogen function, is a different condition.)
