Genes affected

VWF (HGNC:12726): (von Willebrand factor) This gene encodes a glycoprotein involved in hemostasis. The encoded preproprotein is proteolytically processed following assembly into large multimeric complexes. These complexes function in the adhesion of platelets to sites of vascular injury and the transport of various proteins in the blood. Mutations in this gene result in von Willebrand disease, an inherited bleeding disorder. An unprocessed pseudogene has been found on chromosome 22. [provided by RefSeq, Oct 2015]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM1

In a disulfide_bond (size 186) in uniprot entity VWF_HUMAN there are 58 pathogenic changes around while only 4 benign (94%) in NM_000552.5

PP2

Missense variant in the VWF gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 149 curated pathogenic missense variants (we use a threshold of 10). The gene has 28 curated benign missense variants. Gene score misZ: 0.98969 (below the threshold of 3.09). Trascript score misZ: 3.5064 (above the threshold of 3.09). GenCC associations: The gene is linked to von Willebrand disease type 2M, hereditary von Willebrand disease, von Willebrand disease type 2B, von Willebrand disease type 2N, von Willebrand disease 2, von Willebrand disease type 2A, von Willebrand disease 3, von Willebrand disease 1.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.918

BS2

High AC in GnomAdExome4 at 19 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The VWF c.4238C>T (p.Pro1413Leu) variant has been reported in the published literature in multiple individuals with Von Willebrand disease type 1 (PMIDs: 16985174 (2007), 17190853 (2007), 18230755 (2008), 21534937 (2011), 22871923 (2012), 27076201 (2016), 28971901 (2017), 31249928 (2018), and 33134807 (2020)). In vitro expression studies indicated that this variant has no effect on vWF protein function (PMID: 27483487 (2017)) but further studies are required to determine the global effect of this variant on vWF protein function. The frequency of this variant in the general population, 0.000011 (3/282514 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -

The VWF c.4238C>T variant is predicted to result in the amino acid substitution p.Pro1413Leu. This variant has been reported in individuals with Von Willebrand disease 1 (Goodeve et al. 2007. PubMed ID: 16985174; Manderstedt et al. 2018. PubMed ID: 31249928; Dubois et al. 2020. PubMed ID: 33134807). In Manderstedt et al., this variant occurred together with another variant (p.Gly1672Arg), indicating these two variants occur on the same haplotype (Manderstedt et al. 2018. PubMed ID: 31249928). Functional studies using protein expression in cell culture found that the p.Pro1413Leu substitution did not significantly affect protein function (Berber et al. 2016. PubMed ID: 27483487). This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-6128346-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
