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 Likely_benign. Variant got -4 ACMG points.

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.01405701).

BS2

High AC in GnomAd4 at 7 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.1205G>A; p.Arg402Lys variant (rs779082753), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 439321). This variant is found in the Admixed American population with an allele frequency of 0.24% (85/35,402 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is neutral (REVEL: 0.078). However, given the lack of clinical and functional data, the significance of this variant is uncertain at this time. -
