Variant chr12-5949056-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM1PM2PP2PP3

The ENST00000261405.10(VWF):c.8401G>A(p.Ala2801Thr) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,736 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. A2801D) 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]

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

PM1

In a domain CTCK (size 88) in uniprot entity VWF_HUMAN there are 5 pathogenic changes around while only 1 benign (83%) in ENST00000261405.10

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), VWF. . Gene score misZ 0.98969 (greater than the threshold 3.09). Trascript score misZ 3.5064 (greater than threshold 3.09). GenCC has associacion of gene with 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.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.757
