The Different Components of Von Willebrand's Disease

The most recent guidelines do say that like less than 50 if you have bleeding symptoms is classified as von Willebrand's disease. Because it's autosomal dominant, because 70 or 80% is this type one, presumably there is a varying phenotype and some individuals have more severe disease. And even within that, there's not like a super consistent correlation between levels and phenotypes. It can be quite different depending on the patient.
