Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BA1BP4

This summary comes from the ClinGen Evidence Repository: The NM_000552.4(VWF):c.4693G>T (p.Val1565Leu) missense variant has a Grpmax filtering allele frequency in gnomAD v4.1 is 0.3882 (based on 17604/44790 alleles in the east Asian population, including 3463 homozygotes), which is higher than the ClinGen VWD VCEP threshold of >0.1 for BA1. The computational predictor REVEL gives a score of 0.183, 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 benign for von Willebrand disease based on the ACMG/AMP criteria applied, as specified by the ClinGen VWD VCEP: BA1, 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]
