How do you get VWD?

VWD is usually inherited. It is passed down through the genes from either parent to a child of either sex. Sometimes, there is evidence of a family history of bleeding problems, but the symptoms of VWD can vary a lot within a family. Sometimes VWD occurs due to a spontaneous change in the VWD gene before the baby is born.

Inheritance of von Willebrand disease

VWD Types 1 and 2 are usually inherited in what is known as a "dominant" pattern. This means that a parent who has VWD has a one in two (50%) chance of passing a VWD gene on to each of his or her children.

Type 3 VWD, however, is usually inherited in a "recessive" pattern. This type occurs when the child inherits the gene from both parents. Even if both parents have mild symptoms or no symptoms at all, their children may be severely affected.
