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 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.4014171).

The Leu5698Val variant in GPR98 has not been previously reported in individuals with hearing loss or in large population studies. Computational analyses (bioch emical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do n ot provide strong support for or against an impact to the protein. In summary, a dditional information is needed to determine the clinical significance of this v ariant. -

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. 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. ClinVar contains an entry for this variant (Variation ID: 163625). This variant has not been reported in the literature in individuals affected with ADGRV1-related conditions. This variant is present in population databases (rs727503084, gnomAD 0.001%). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 5698 of the ADGRV1 protein (p.Leu5698Val). -
