[MIM*134820] An autosomal dominant disorder of qualitatively abnormal fibrinogens of various types; each type is named for the city in which the abnormal fibrinogen was discovered. Examples include: 1) Amsterdam, Bethesda II, Cleveland, Los Angeles, Saint Louis, Zurich I and II: major defect, aggregation of fibrin monomers; thrombin time prolonged; inhibitory effect on normal clotting; asymptomatic; 2) Bethesda I and Detroit: major defect, fibrinopeptide release; thrombin time prolonged; inhibitory effect on normal clotting; abnormal bleeding; 3) Baltimore: major defect, fibrinopeptide release; thrombin time prolonged; no inhibitory effect on normal clotting; bleeding and thrombosis; 4) Leuven: major defect, questionable aggregation of fibrin monomers; thrombin time prolonged; slight inhibitory effect on normal clotting; abnormal bleeding; 5) Metz: major defect unreported; thrombin time infinite; effect on normal clotting unreported; abnormal bleeding; 6) Nancy: major defect, aggregation of fibrin monomers; thrombin time prolonged; slight inhibitory effect on normal clotting; asymptomatic; 7) Oklahoma: major defect unreported; thrombin time normal; no effect on normal clotting; abnormal bleeding; 8) Oslo: major defect unreported; thrombin time shortened; effect on normal clotting unreported; abnormal thrombosis; 9) Parma: major defect unreported; thrombin time infinite; no inhibitory effect on normal clotting; abnormal bleeding; 10) Paris I: major defect unreported; thrombin time infinite; inhibitory effect on normal clotting; asymptomatic; 11) Paris II: major defect unreported; thrombin time prolonged; inhibitory effect on normal clotting; asymptomatic; 12) Troyes: major defect unreported; thrombin time prolonged; effect on normal clotting unreported; asymptomatic; 13) Vancouver: major defect unreported; thrombin time prolonged; no effect on normal clotting; abnormal bleeding; 14) Wiesbaden: major defect, aggregation of fibrin monomers; thrombin time prolonged; inhibitory effect on normal clotting; bleeding and thrombosis.
