In contrast, our understanding of the molecular pathogenesis of the most common form of VWD, type 1 disease, is still at an early stage, with preliminary evidence that this phenotype involves a complex interplay between environmental factors and the influence of genetic variability both within and outside of the VWF locus.

These studies show that cultured umbilical vein endothelial cells can be used to explore the molecular defects in type I and perhaps other forms of vWD, and suggest that at least some forms of type I vWD are caused by diminished mRNA transcription or subsequent translation due to a defective vWF allele.

This strongly suggests that type I vWD Vicenza is due to a mutation in one of the vWF alleles, which results in an abnormal vWF molecule that is processed to a lesser extent than normal vWF.

In order to better characterize the genotype-phenotype correlation in type 2M von Willebrand disease (VWD), we sequenced the coding region for the mature subunit of the von Willebrand factor (VWF) gene (exons 18-52, including exon/intron boundaries) in 16 index cases originally submitted to the Canadian Type 1 VWD Study as type 1 VWD, but reclassified as type 2M VWD on the basis of phenotype (excessive mucocutaneous bleeding and von Willebrand factor: antigen (VWF:Ag) and/or von Willebrand factor: ristocetin cofactor (VWF:RCo) between 0.05 and 0.50 IU mL(-1) on at least two occasions and RCo/Ag ratio < 0.6 and no loss of high molecular weight multimers).
