Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS1

This summary comes from the ClinGen Evidence Repository: NM_000552.5(VWF):c.5173C>T is a missense variant that replaces proline with serine at position 1725. TThe Grpmax filtering allele frequency in gnomAD v4.1 is 0.02354 (based on 1836/75022 alleles in the African / African-American population, with 27 homozygotes), which is higher than the ClinGen VWD VCEP threshold of >0.01 for BS1. While this variant has been reported in healthy control individuals (PMID:22197721), BS2 is not being used due to penetrance issues. In summary, this variant meets the criteria to be classified as Likely Benign for hereditary von Willebrand disease based on the ACMG/AMP criteria applied, as specified by the ClinGen VWD VCEP: BS1.

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]
