Clinical and laboratory phenotype variability in type 2M von Willebrand disease.

ABSTRACT: Essentials The pathophysiology of type 2M von Willebrand disease (VWD) is poorly understood. Sequence variations in type 2M VWD subjects were characterized. A high degree of clinical and laboratory variability exists within type 2M VWD variants. Some type 2M variants may share features of type 2A VWD.

Summary

Background von Willebrand factor (VWF) is a multimeric coagulation factor that tethers platelets to injured subendothelium. Type 2M von Willebrand disease (VWD) is characterized by a qualitative defect in VWF with preserved multimer distribution. Objectives Through the Zimmerman Program for the Molecular and Clinical Biology for VWD, five VWF sequence variations were studied in subjects diagnosed with type 2M VWD. Methods Bleeding phenotype was assessed using the ISTH bleeding
