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).;
