Von Willebrand disease (VWD) is the most common hereditary blood-clotting disorder in humans. An acquired form can sometimes result from other medical conditions. [ 1 ] It arises from a deficiency in the quality or quantity of von Willebrand factor (VWF), a multimeric protein that is required for platelet adhesion .
Von Willebrand was born on 1 February 1870 in Nikolainkaupunki, then part of the Grand Duchy of Finland in the Russian Empire. [1] He was the third child of Fredrik Magnus von Willebrand and Signe Estlander. [2] [3] Fredrik had received a military education and later became an engineer. [3]
Von Willebrand factor (VWF) (German: [fɔn ˈvɪləbʁant]) is a blood glycoprotein that promotes primary hemostasis, specifically, platelet adhesion. It is deficient and/or defective in von Willebrand disease and is involved in many other diseases, including thrombotic thrombocytopenic purpura , Heyde's syndrome , and possibly hemolytic ...
The von Willebrand factor type A (vWA) domain is a protein domain named after its occurrence in von Willebrand factor (vWF), a large multimeric glycoprotein found in blood plasma. Mutant forms of vWF are involved in the aetiology of bleeding disorders. [ 2 ]
ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13)—also known as von Willebrand factor-cleaving protease (VWFCP)—is a zinc-containing metalloprotease enzyme that cleaves von Willebrand factor (vWf), a large protein involved in blood clotting.
Von Willebrand factor type D domain (vWD) is an evolutionarily-conserved protein domain found in, among others, the von Willebrand factor (vWF). vWF is a large multimeric glycoprotein and it is synthesized by a type of bone marrow cell called megakaryocytes. The vWD domain allows vWF to perform its blood-clotting function by carrying factor ...
In the case of type 2B vWD, the gain-of-function mutation involves von Willebrand's factor (VWF gene), and in platelet-type vWD, the receptor is the object of the mutation (GPIb). This increased binding causes vWD because the high-molecular weight multimers are removed from circulation in plasma since they remain attached to the patient's ...
Willebrand or Willebrands may refer to: Von Willebrand disease, a hereditary coagulation abnormality disease; Von Willebrand factor, a blood glycoprotein involved in hemostasis; Erik Adolf von Willebrand, a Finnish internist; Julia Willebrand, an environmental, peace and education activist; Johannes Willebrands, a Dutch Cardinal of the Roman ...
