Evidence submitted by expert panel
von Willebrand Disease VCEP
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.

BS1
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).
BP4
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 gives a score of 0.00 for all splicing types, indicating that the variant has no impact on splicing.
