Summary Summary

Von Willebrand disease is a bleeding disorder that slows the blood clotting process. People with this disease often experience bruising, nosebleeds, and prolonged bleeding or oozing following an injury, affer surgery, or having a tooth pulled. Affected women may have heavy menstrual bleeding. In severe cases, heavy bleeding occurs after minor injury or even in the absence of injury. It is divided into three types. Type 1 is the mildest and most common, and type 3 is the most severe and rarest form. Type 2 (four subtypes) is intermediate in severity. Increased age, pregnancy, exercise, and stress may cause von Willebrand factor levels in the blood to rise, which can make bleeding symptoms less frequent. This disease is caused by mutations in the VWF gene and can have different inheritance patterns.^[1] Treatment varies according to the severity of the disease and includes plasma-derived clotting factor concentrates, and other medications.^[2]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause

Von Willebrand disease is typically an inherited disease caused by variations (mutations) in the VWF gene. The VWF gene provides instructions for making a blood clotting protein called von Willebrand factor, which is important for forming blood clots and preventing further blood loss after an injury. If von Willebrand factor does not function normally or too little of the protein is available, blood clots cannot form properly. VWF gene mutations that reduce the amount of von Willebrand factor or cause the protein to function abnormally (or not at all) are responsible for the signs and symptoms associated with the condition. These variations may be inherited in an autosomal dominant or autosomal recessive manner, or may occur for the first time in the affected person without any other cases in the family. (known as a de novo mutation).^[3]

There is another condition, called acquired von Willebrand syndrome (AVWS) that is not caused by gene mutations, and is not inherited. This condition may be part of other disorders and usually begins in adulthood.^[3] A list of disorders associated with AVWS is available from UpToDate.^[4]

Inheritance Inheritance

Most, but not all, cases of von Willebrand disease (VWD) are inherited. The majority of cases of type 1 and type 2A, as well as type 2B and type 2M, are inherited in an autosomal dominant manner. VWD type 2N, type 3, and some cases of type 1 and type 2A are inherited in an autosomal recessive manner.^[5]

Most individuals with an autosomal dominant type of VWD have an affected parent. However, some individuals are affected due to having a new (de novo) mutation in the VWF gene that occurred for the first time in the affected individual. If the mutation found in the affected individual cannot be detected in either parent, it is most often due to a de novo mutation but may also be due to germline mosaicism in a parent. Possible non-medical explanations which may be explored include alternate paternity or maternity (e.g., with assisted reproduction) or undisclosed adoption.^[5]

Another rare and different condition called acquired von Willebrand syndrome (AVWS). is a mild to moderate bleeding disorder that is typically seen in conjunction with other disorders, such as diseases that affect bone marrow or immune cell function. AVWS is not caused by a mutation in the VWF gene and usually begins in adulthood.^[5]^[3]

Related diseases are conditions that have similar signs and symptoms. A health care provider may consider these conditions in the table below when making a diagnosis. Please note that the table may not include all the possible conditions related to this disease.

Conditions with similar signs and symptoms from Orphanet
Measurements of VWF levels generally allow VWD to be distinguished from hemophilia A (see this term). However, this test does not allow differentiation of type 2N VWD, which requires more specific tests. Differentiation between acquired von Willebrand syndrome (AVWS; see this term), which occurs in association with another underlying pathology, and inherited VWD is more problematic. The fact that individuals in the general population belonging to blood group O may also have moderately lower levels of VWF should also be taken into consideration in the differential diagnosis. Visit the Orphanet disease page for more information.
