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 Uncertain_significance. Variant got 2 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

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.

BS2

High AC in GnomAdExome4 at 23 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
