Rapid genotypic diagnosis of type 2A von Willebrand's disease by heteroduplex analysis.
We have previously reported a rapid heteroduplex-based technique which is able to identify at least 10 recurrent mutations associated with type 2A von Willebrand's disease. Thirteen patients with this disorder were genotyped by this method and a specific mutation was identified in nine cases. This simple DNA based approach can provide useful information to support data derived from phenotype tests in the initial assessment of such patients.
