ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PP5

Variant 11-124897049-C-T is Pathogenic according to our data. Variant chr11-124897049-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 560395.Status of the report is criteria_provided_single_submitter, 1 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.013157159). . Strength limited to SUPPORTING due to the PP5.

BS2

High AC in GnomAd4 at 10 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

clinical testing

PreventionGenetics, part of Exact Sciences

Jun 11, 2024

The ROBO4 c.283G>A variant is predicted to result in the amino acid substitution p.Ala95Thr. This variant has been reported in an individual with bicuspid aortic valve and thoracic aortic aneurysm (Gould et al 2019. PubMed ID: 30455415). This variant is reported in 0.016% of alleles in individuals of South Asian descent in gnomAD. Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
