Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BA1

This summary comes from the ClinGen Evidence Repository: The NM_000552.4(VWF):c.8113G>A (p.Gly2705Arg) variant in VWF is a missense variant predicted to cause substitution of Glycine by Arginine at amino acid 2705. The Grpmax filtering allele frequency in gnomAD v4.1 is 0.1227 (based on 11352/91062 alleles in the South Asian population, including 829 homozygotes), which is higher than the ClinGen VWD VCEP threshold of >0.1 for BA1. As reported in PMID:26105150 the variant is significantly associated with lower plasma levels of FVIII but not vWF. In summary this variant is classified as Benign for VWD based on the ACMG/AMP criteria applied, as specified by the ClinGen VWD VCEP: BA1 LINK:https://erepo.genome.network/evrepo/ui/classification/CA6401404/MONDO:0019565/090

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]
