Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4BS1

This summary comes from the ClinGen Evidence Repository: NM_000552.5(VWF):c.7997C>T is a missense variant that substitutes threonine for methionine at position 2666. The Grpmax filtering allele frequency in gnomAD v4.0 is 0.06826 (based on 5238/74998 alleles in the African/African American population) which is higher than the ClinGen VWD VCEP threshold (>0.01) for BS1, and therefore meets this criterion (BS1). While this variant has been observed in healthy control individuals (PMID:22197721), BS2 is not being used due to penetrance issues. The computational predictor REVEL gives a score of 0.027, which is below the ClinGen VWD VCEP threshold of <0.290 and does not predict a damaging effect on VWF function (BP4). Additionally, the computational splicing predictor SpliceAI indicated that the variant has no impact on splicing. In summary, this variant meets the criteria to be classified as likely benign for von Willebrand disease based on the ACMG/AMP criteria applied, as specified by the ClinGen VWD VCEP: BS1, BP4.

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]
