Variant summary

Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PS3PM5PP2PP3PP5_Very_Strong

The NM_000552.5(VWF):c.3613C>T(p.Arg1205Cys) variant causes a missense change. The variant allele was found at a frequency of 0.00000929 in 1,614,142 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV002559372: Published functional studies demonstrate a damaging effect with enhanced clearance of von Willebrand factor by macrophages (Rawley et al., 2015)" and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1205H) has been classified as Pathogenic. The gene VWF is included in the ClinGen Criteria Specification Registry.

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]

ACMG classification

Specifications for VWF are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Pathogenic. The variant received 16 ACMG points.

PS3

PS3 evidence extracted from ClinVar submissions: SCV002559372: Published functional studies demonstrate a damaging effect with enhanced clearance of von Willebrand factor by macrophages (Rawley et al., 2015); PMID: 31064749, 19630772, 25690668, 16321553, 20230424, 18449422, 32108991, 16925796; SCV002598665: "At least one publication reports experimental evidence evaluating an impact on protein function resulting from significantly reduced survival of full-length VWf fragments within the cell (Rawley_2015)." PMID:26986123

PM5

Other missense variant is known to change same aminoacid residue: Variant chr12-6021960-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 308.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PP2

Missense variant in the VWF gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 149 curated pathogenic missense variants (we use a threshold of 10). The gene has 28 curated benign missense variants. Gene score misZ: 0.98969 (below the threshold of 3.09). Trascript score misZ: 3.5064 (above the threshold of 3.09). GenCC associations: The gene is linked to von Willebrand disease type 2N, von Willebrand disease type 2B, von Willebrand disease type 2M, von Willebrand disease 2, hereditary von Willebrand disease, von Willebrand disease type 2A, von Willebrand disease 1, von Willebrand disease 3.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.837

PP5

Variant 12-6021961-G-A is Pathogenic according to our data. Variant chr12-6021961-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 439332.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
