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 Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.87).

BP6

Variant 12-6072363-G-A is Benign according to our data. Variant chr12-6072363-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 310086.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.

BP7

Synonymous conserved (PhyloP=-2.37 with no splicing effect.

BS2

High AC in GnomAd4 at 96 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
