A subtype of type 2 VWD characterized by a bleeding disorder associated with an increase in the affinity of the Willebrand factor (von Willebrand factor; VWF) for platelets. This anomaly results in spontaneous binding of high molecular weight VWF multimers to platelets leading to rapid clearance of both the platelets (increasing the risk of thrombocytopenia) and the high molecular weight VWF multimers from the plasma.
Biomarker and diagnostic research for von Willebrand disease type 2B has been reported in the published literature.
Estimated prevalence: Unknown (Unknown prevalence).
No clinical trials have been registered for von Willebrand disease type 2B.
4 publications have been identified in PubMed for von Willebrand disease type 2B. Research spans Diagnostic / Biomarker (50%), Basic Science / Preclinical (25%), and Gene Therapy / Novel Therapeutics (25%).
