Summary Summary


Listen
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]

Cause Cause


Listen
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]
Last updated: 2/21/2018

Inheritance Inheritance


Listen
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]

Treatment Treatment


Listen

The resources below provide information about treatment options for this condition. If you have questions about which treatment is right for you, talk to your healthcare professional.

Management Guidelines

  • The National Hemophilia Foundation Web site posts the guidelines for management of pregnancy and delivery of women with bleeding disorders and carriers of hemophilia A and B. Click on the link to view the guidelines.
  • Project OrphanAnesthesia is a project whose aim is to create peer-reviewed, readily accessible guidelines for patients with rare diseases and for the anesthesiologists caring for them. The project is a collaborative effort of the German Society of Anesthesiology and Intensive Care, Orphanet, the European Society of Pediatric Anesthesia, anesthetists and rare disease experts with the aim to contribute to patient safety.
  • The National Heart, Blood and Lung Institute (NHLBI) assembled a panel of experts on von Willebrand to develop clinical management guidelines. To view the guidelines, click on the link.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from Genetics Home Reference.
  • The Division of Blood Disorders at the Centers for Disease Control and Prevention has created specialized programs for persons with blood disorders and their families. One of the activities of the division involves the collaboration with networks of specialized health care centers throughout the United States.

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.
