Description : Von Willebrand disease is a bleeding disorder resulting from a defect in platelet aggregation due to defects in the von Willebrand factor protein. Type 3 von Willebrand disease, which is inherited as an autosomal recessive disorder, is associated with a severe quantitative defect or virtual absence of VWF in plasma, a prolonged bleeding time, and more severe bleeding tendencies compared to the other types of VWD. Type 3 accounts for about 1% of patients with VWD. Bleeding usually starts in infancy and can include epistaxis, recurrent mucocutaneous bleeding, bleeding after surgery, and hemarthroses. Since VWF also serves as a carrier protein for coagulation factor VIII (F8; 300841), affected individuals also have very low levels of plasma F8, resembling hemophilia A (306700) (summary by Zhang et al., 1992, 1993; reviews by Sadler et al., 2006 and Lillicrap, 2009). For a general description and a classification of the types of von Willebrand disease, see VWD type 1 (193400).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the von Willebrand factor gene (VWF, 613160.0015);

Laboratory abnormalities : Severely decreased antigen levels of VWF and factor VIII;

Prefixed ID : #277480;
