Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV003323716 SCV004028808 uncertain significance not specified 2023-07-24 criteria provided, single submitter clinical testing Variant summary: VWF c.5170+5G>A alters a conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. Several computational tools predict a significant impact on normal splicing: Three predict the variant abolishes the canonical 5' splicing donor site, and two predict the variant abolishes a cryptic 5' donor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 251478 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.5170+5G>A has been reported in the literature in an individual affected with a coagulation condition (Downes_2019); however, this report does not provide unequivocal conclusions about association of the variant with Von Willebrand Disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 31064749). Two submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.
