Inherited disorders of fibrinogen affect either the quantity (afibrinogenemia and hypofibrinogenemia; 202400) or the quality (dysfibrinogenemia) of the circulating fibrinogen, or both (hypodysfibrinogenemia). Patients with dysfibrinogenemia are frequently asymptomatic, but some patients have bleeding diathesis, thromboembolic complications, or both (summary by de Moerloose and Neerman-Arbez, 2009). Reports (e.g., Haverkate and Samama, 1995) on approximately 350 families with dysfibrinogenemia revealed that approximately half of cases are clinically silent, a quarter show a tendency toward bleeding, and another quarter show a predisposition for thrombosis with or without bleeding (summary by Lefebvre et al., 2004).
