Pittsburgh Clinical Genomics Laboratory, University of Pittsburgh Medical Center RCV004784991 SCV005397340 uncertain significance von Willebrand disease type 1 2023-10-12 criteria provided, single submitter clinical testing This sequence variant is a single nucleotide substitution (G>A) at position 976 of the coding sequence of the VWF gene that results in a valine to methionine amino acid change at residue 326 of the von Willebrand factor protein. The 326 residue falls in the domain first trypsin-inhibitor-like domain (UniProt, PMID: 22490677). This variant is absent from ClinVar. This variant is absent from the gnomAD population database (0/~250,000 alleles). Multiple bioinformatic tools predict that this Val to Met amino acid change would be neutral, and the Val326 residue at this position is highly conserved across the vertebrate species examined. Studies examining the functiol consequence of this variant have not been published, to our knowledge. At this time, there is insufficient evidence to determine if this variant is pathogenic or benign. Therefore, we consider this a variant of uncertain significance. ACMG Criteria: PM2, PP2
