von Willebrand Disease
Medical Dictionary
Definition of medical terminology for von Willebrand Disease.
Von Willebrand disease is broadly divided into three types based on von Willebrand factor levels. Mutations in the VWF gene that reduce the amount of von Willebrand factor cause type 1 von Willebrand disease.
VON WILLEBRAND DISEASE OVERVIEW
When people think of medical disorders that cause excessive or uncontrolled bleeding, they usually think of hemophilia. That's understandable, given that hemophilia is often mentioned in popular culture.
Von Willebrand disease (VWD) is a bleeding disorder. It affects your blood's ability to clot. If your blood doesn't clot, you can have heavy, hard-to-stop bleeding after an injury. The bleeding can damage your internal organs.

von Willebrand disease - a part of the factor VIII molecule known as von Willebrand factor or ristocetin cofactor is reduced.
Von Willebrand disease is almost always inherited. This means that parents pass a gene for the disease on to their children. The gene for the disease is usually dominant .

The factor VIII assay is a blood test that measures the activity of factor VIII -- one of the substances involved in blood clotting (coagulation).

Von Willebrand disease is an inherited condition that results when the blood lacks von Willebrand factor, a protein that helps the blood to clot and also carries another clotting protein, factor VIII.
von Willebrand disease can often be traced through several generations in a family. Some have symptoms, while others just carry the gene. Most people with vWD inherit only one gene with the vWD defect.
Von Willebrand disease (VWD) is an inherited disorder that affects the blood's ability to clot. People with VWD may experience heavy bleeding after an injury, leading to physical damage or even death.

von Willebrand disease - a form of hemophilia caused by an abnormality in the von Willebrand factor, which is necessary for platelets to be able to attach themselves to a vein or artery to form a clot to stop bleeding.

With von Willebrand disease, the missing protein, von Willebrand factor (vWF), is not on the X chromosome, but on a chromosome that is not gender determined; so, the disease can affect both males and females equally.
Definition Von Willebrand disease is caused by a deficiency or an abnormality in a protein called vonWillebrand factor and is characterized by prolonged bleeding.

Von Willebrand Disease and Other Bleeding Disorders. Bleeding disorders that stop blood from clotting can cause heavy menstrual bleeding. Most of these disorders have a genetic basis.
Another reason that some people bruise easily is a rare genetic disorder called von Willebrand disease, which prevents the blood from clotting properly. This disorder affects at least 1% of the population.
The most common bleeding disorder is von Willebrand disease (VWD). VWD results from a deficiency or defect in the body's ability to make von Willebrand factor, a protein that helps blood clot.
Von Willebrand disease, a genetic condition, is the most common of these bleeding disorders. Most, but not all, studies report this problem to be more common in African American than Caucasian women.
von Willebrand disease
Symptoms:
The main symptom of hemophilia is bleeding. Mild cases may go unnoticed until later in life, when they occur in response to surgery or trauma. Internal bleeding may occur anywhere. Bleeding into joints is common.
When blood does not clot effectively, as occurs with certain conditions, such as hemophilia or von Willebrand disease, even a minor injury to a blood vessel may lead to serious blood loss.
Some people have genetic or inborn errors of the blood clotting system. Minor injuries may cause major bleeding in these cases. Hemophilia and von Willebrand disease are two examples.
