ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0149948895).

BS2

High AC in GnomAd4 at 8 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Ambry Genetics

Jul 06, 2022

The c.43G>A (p.G15S) alteration is located in exon 1 (coding exon 1) of the VWA8 gene. This alteration results from a G to A substitution at nucleotide position 43, causing the glycine (G) at amino acid position 15 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
