Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV002222391 SCV002500602 pathogenic Hereditary von Willebrand disease 2022-03-23 criteria provided, single submitter clinical testing Variant summary: VWF c.4628C>T (p.Ser1543Phe) results in a non-conservative amino acid change located in the type A2 domain (IPR002035), which is considered to be a shear-sensor domain, regulated by hydrodynamic shear force-dependent unfolding (Zhang_2009). Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 250514 control chromosomes (gnomAD). The variant c.4628C>T (aka. Ser780Phe) has been reported in the literature in heterozygous state in multiple individuals affected with Type2A von Willebrand Disease (Meyer_1997, Gindele_2021), and in one of these reports the variant showed segregation with the phenotype in a family (Gindele_2021). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic.
