VWF propeptide in defining VWD subtypes

Abstract

In this issue of Blood, Sanders and coworkers define the pathophysiology of types 1, 2, and 3 von Willebrand disease (VWD) in the Willebrand in the Netherlands (WiN) study by using the ratios of von Willebrand factor propeptide (VWFpp) or factor VIII activity to VWF antigen.
