patients with type IIC von Willebrand disease

Genetic studies were performed in two unrelated patients with the IIC
phenotype of von Willebrand disease (vWD) characterized by the increased
concentration of the protomeric form of von Willebrand factor (vWF). In
patient B, the sequencing of both exons 15 and 16 of the vWF gene showed
two sequence alterations: a 3-bp insertion in exon 15 resulting in the
insertion of a Glycine at position 625 (625insGly) and a 2-bp deletion in
exon 16 leading to a premature translational stop at codon 711 (711 ter),
at the heterozygote state. Patient A was found homozygous for a single
point mutation also localized in exon 15 and responsible for the
substitution Cys623Trp. These candidate mutations were not found in a panel
of 96 normal chromosomes, suggesting a causal relationship with IIC vWD
phenotypic expression. The composite heterozygote or homozygote state of
both patients supports the recessive mode of inheritance already described
for this phenotype. Furthermore, the localization of these gene defects in
the D2 domain of vWF propeptide, known to play an important role in vWF
multimerization, provides another argument in favor of their causative
effect regarding the peculiar multimeric pattern of vWF in these patients.
