A new case of platelet-type von Willebrand disease supports the recent findings of gain-of-function GP1BA variants outside the C-terminal disulphide loop enhances affinity for von Willebrand factor.
Differential identification of a rare form of platelet-type (pseudo-) von Willebrand disease (VWD) from Type 2B VWD using a simplified ristocetin-induced-platelet-agglutination mixing assay and confirmed by genetic analysis.
