Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM1PP2PP3_Moderate

The NM_000552.5(VWF):c.4000C>T(p.Arg1334Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000242 in 1,613,806 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 Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1334Q) has been classified as Uncertain significance.

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 was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM1

In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_000552.5

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

PP3

MetaRNN computational evidence supports a deleterious effect, 0.914
