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]

The p.Gly2957Glu variant in GPR98 has not been previously reported in individual s with hearing loss or Usher syndrome. This variant has been identified in 1/584 10 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.b roadinstitute.org; dbSNP rs762211616). Computational prediction tools and conser vation analysis suggest that the p.Gly2957Glu variant may impact the protein, th ough this information is not predictive enough to determine pathogenicity. In su mmary, the clinical significance of the p.Gly2957Glu variant is uncertain. -

ClinVar contains an entry for this variant (Variation ID: 505299). This variant has not been reported in the literature in individuals affected with ADGRV1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 2957 of the ADGRV1 protein (p.Gly2957Glu). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. -
