Autosomal inheritance with variable penetrance and phenotypic expression.
Usually presents with mucocutaneous bleeding.
Menorrhagia and postnatal haemorrhage common in affected females.
Joint bleeding rare and seen only in patients with more severe disease.
Most patients have type 1 von Willebrand disease; more severe symptoms are seen in types 2 and 3.
Clinical bleeding scores may be helpful in identifying patients with disease.
Von Willebrand disease (VWD), the most common inherited bleeding disorder, is due to either a quantitative or qualitative abnormality of von Willebrand factor (VWF). VWF provides the critical link between platelets and exposed vascular subendothelium, and also binds and stabilises coagulation factor VIII.
