Von Willebrand disease type 2N

Definition

A subtype of type 2 von Willebrand disease characterized by a bleeding disorder associated with a marked decrease in the affinity of the Willebrand factor (VWF) for factor VIII (FVIII). Abnormal bleeding manifestations are less frequent in this VWD subtype than in other forms of the disease. The disease manifests mainly as soft tissue bleeding (haematoma, post-operative bleeding, etc.).
