ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.020563573).

BS2

High AC in GnomAd4 at 6 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The amino acid Gly at position 920 is changed to a Ser changing protein sequence and it might alter its composition and physico-chemical properties. This variant has not been reported previously in affected individuals. In silico tools predict the variant to be tolerated. The residue is conserved across species. The amino acid change p.Gly920Ser in ROBO4 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates The variant is present in 0.01% individuals in the gnomAD database including one homozygous allele.. This variant is classified as uncertain significance as per ACMG guidelines. -
