Von Willebrand disease is a hereditary disorder. It is caused by an abnormal gene. Each cell of the body contains structures called chromosomes. A chromosome is a long chain of chemicals known as DNA. This DNA is arranged into about 25,000 units called genes which determine such things as the colour of a personâs eyes. Each cell contains 46 of these chromosomes arranged in 23 pairs. Von Willebrand disease is caused by a defect on chromosome 12. The defect could be on the chromosome 12 from the mother, on the chromosome 12 from the father, or on both. There are two ways of getting the hereditary form of VWD.
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. Rarely, the bleeding may even cause death. In VWD, you either have low levels of a certain protein in your blood or the protein doesn't work well. The protein is called von Willebrand factor, and it helps your blood clot. Normally, when one of your blood vessels is injured, you start to bleed.
