Variant summary

Our verdict is Benign. Variant got -15 ACMG points: 5P and 20B. PM1PM5PP2BP4_StrongBP6_Very_StrongBA1

The NM_000552.5(VWF):c.2365A>G(p.Thr789Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.356 in 1,613,858 control chromosomes in the GnomAD database, including 107,997 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T789P) has been classified as Likely pathogenic.

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

Classification made for transcript

Verdict is Benign. Variant got -15 ACMG points.

PM1

In a domain TIL 3 (size 51) in uniprot entity VWF_HUMAN there are 12 pathogenic changes around while only 0 benign (100%) in NM_000552.5

PM5

Other missense variant is known to change same aminoacid residue: Variant chr12-6044368-T-G is described in Lovd as [Likely_pathogenic].

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 2M, hereditary von Willebrand disease, von Willebrand disease type 2B, von Willebrand disease type 2N, von Willebrand disease 2, von Willebrand disease type 2A, von Willebrand disease 3, von Willebrand disease 1.

BP4

Computational evidence support a benign effect (MetaRNN=6.430792E-5).

BP6

Variant 12-6044368-T-C is Benign according to our data. Variant chr12-6044368-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 256659.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr12-6044368-T-C is described in Lovd as [Benign]. Variant chr12-6044368-T-C is described in Lovd as [Likely_benign].

BA1

GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.57 is higher than 0.05.
