Genes affected

ADGRV1 (HGNC:17416): (adhesion G protein-coupled receptor V1) This gene encodes a member of the G-protein coupled receptor superfamily. The encoded protein contains a 7-transmembrane receptor domain, binds calcium and is expressed in the central nervous system. Mutations in this gene are associated with Usher syndrome 2 and familial febrile seizures. Several alternatively spliced transcripts have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.746

The p.Asp3726Glu variant in ADGRV1 has not been reported in individuals with Ush er syndrome or in large population studies. Computational prediction tools and c onservation analysis suggest that the p.Asp3726Glu variant may impact the protei n, though this information is not predictive enough to determine pathogenicity. In summary, while the clinical significance of the p.Asp3726Glu variant is uncer tain. ACMG/AMP Criteria applied: PM2, PP3. -

This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 3726 of the ADGRV1 protein (p.Asp3726Glu). This variant has not been reported in the literature in individuals affected with ADGRV1-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ADGRV1 protein function. ClinVar contains an entry for this variant (Variation ID: 517637). -
