A standard nomenclature for von Willebrand factor gene mutations and polymorphisms

Mutations in the von Willebrand factor gene responsible for von Willebrand disease, in particular those responsible for type 2 von Willebrand disease, are being increasingly identified. The plethora of mutation screening tech niques now available and their enhanced sample throughput capability is als o enabling an increasing number of investigations in patients with types 1 and 3 disease. An unambiguous von Willebrand factor nucleotide and amino ac id nomenclature is now essential. In this paper, we present a uniform stand ard nomenclature for von Willebrand factor gene mutations and polymorphisms as approved and recommended by the International Society on Thrombosis and Haemostasis Scientific and Standardisation Committee subcommittee on von W illebrand factor.
