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]

Computational evidence support a benign effect (BayesDel_noAF=-0.73).

BP6

Variant 12-6016550-G-A is Benign according to our data. Variant chr12-6016550-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 310061.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=3}. Variant chr12-6016550-G-A is described in Lovd as [Benign].

BP7

Synonymous conserved (PhyloP=0.158 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00793 (1208/152296) while in subpopulation NFE AF= 0.0138 (937/68024). AF 95% confidence interval is 0.013. There are 7 homozygotes in gnomad4. There are 574 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2

High AC in GnomAd4 at 1208 AD gene.
