Fibrinogen Marseille. A new case of congenital dysfibrinogenaemia

A new case of congenital dysfibrinogenaemia was found in 2 members of the same family. The anomaly was characterized by an abnormal polymerization of fibrin monomers, whereas the release of fibrinopeptides by thrombin and fibrin stabilization by F XIII were normal. Investigation of the fibrinogen molecule did not lead to localizing the structural abnormality.
