Von Willebrand disease, type 2B: Introduction. Von Willebrand disease, type 2B: A rare inherited blood coagulation disorder characterized by a defect in plasma protein called the von Willebrand factor which leads to bleeding problems. Type 2 vWD is further subdivided into 4 subtypes, each with a different underlying genetic defect.
von Willebrand disease (VWD) is the most common bleeding disorder, with a prevalence of up to 1%. VWD is caused by either a quantitative or qualitative defect of von Willebrand factor (VWF), which mediates platelet adhesion by binding to the GP1b platelet glycoprotein and to collagen on injured blood vessels.
