Von Willebrand disease type 2 – http://id.who.int/icd/entity/1658351780

Type 2 von Willebrand disease is a form of VWD characterised by a bleeding disorder associated with a qualitative deficiency and functional anomalies of the Willebrand factor (von Willebrand factor; VWF). The type 2 disease accounts for between 20 and 45% of cases of VWD. Age of onset of the bleeding anomalies varies, with earlier onset being associated with more severe VWF deficiency. Four type 2 VWD subtypes have been described (types 2A, 2B, 2M and 2N).
