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]
RN7SL69P (HGNC:46085): (RNA, 7SL, cytoplasmic 69, pseudogene)

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP6
Variant 12-6095571-C-T is Benign according to our data. Variant chr12-6095571-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 256684.
BS2
High Homozygotes in GnomAdExome4 at 6 AD,AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
