Abnormal values are highlighted in bold. Mutations are indicated by amino acid substitutions (https://www.omim.org/entry/613160#73, www.VWF.group.shef.ac.uk; last accessed 18 December 2021). Patients 2 and 3 are father and son; patient 5 has an additional amino acid polymorphism p.(V1565L) in the A2 domain.
