Congenital Afibrinogenemia is a rare disorder characterized by absence of a certain substance (protein) in the blood that is essential in the blood clotting (coagulation) process. This protein is known as fibrinogen or coagulation factor I. Affected individuals may be susceptible to severe bleeding (hemorrhaging) episodes, particularly during infancy and childhood. Congenital Afibrinogenemia is thought to be transmitted as an autosomal recessive trait.
