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]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 26, 2024	This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 2756 of the ADGRV1 protein (p.Gly2756Arg). This variant is present in population databases (rs546198768, gnomAD 0.01%). This missense change has been observed in individual(s) with childhood epilepsy (PMID: 29266188). ClinVar contains an entry for this variant (Variation ID: 449252). 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 with a negative predictive value of 80%. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Aug 04, 2023	Observed with the E4410K variant in the ADGRV1 gene in a patient with myoclonic epilepsy in published literature (Myers et al., 2018); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 32962041, 29266188, 34160719) -

The p.Gly2756Arg variant in GPR98 has not been previously reported in individual s with Usher syndrome, but has been identified in 2/35724 European chromosomes b y the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs546198768). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational predi ction tools and conservation analysis suggest that the p.Gly2756Arg variant may impact the protein, though this information is not predictive enough to determin e pathogenicity. In summary, the clinical significance of the p.Gly2756Arg varia nt is uncertain. -
