Summary

A new case of congenital dysfibrinogenemia characterized by a prolonged thrombin clotting time and a low optical density of the polymerization curve has been discovered in Montreal. The functional defect is due to an abnormal aggregation of fibrin monomers.

The characteristics of this abnormal fibrinogen are serum gélification (Paracoagulation) at 37°, 22° and 4° C, a normal immuno-electrophoretic and electrofocusing pattern, a slight increase in the mobility in the α (A) chain by electrophoresis of the dissociated chains in polyacrylamide gel. However, no abnormality was found in the α (A) chain of the disulphide knot.
