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.Arg3804Gln variant in GPR98 has not been previously reported in individual s with hearing loss or Usher syndrome and is absent from large population studie s. Computational prediction tools and conservation analyses suggest that the p.A rg3804Gln variant may impact the protein, though this information is not predict ive enough to determine pathogenicity. In summary, the clinical significance of the p.Arg3804Gln variant is uncertain. -

Review Status:criteria provided, single submitter

Variant summary: ADGRV1 c.11411G>A (p.Arg3804Gln) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 248926 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.11411G>A has been reported in the literature in two siblings from a family affected with hearing loss, without strong evidence for causality (Wu_2020). These report(s) do not provide unequivocal conclusions about association of the variant with Usher Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 32048449). ClinVar contains an entry for this variant (Variation ID: 228704). Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 3804 of the ADGRV1 protein (p.Arg3804Gln). This variant is present in population databases (no rsID available, gnomAD 0.007%). This missense change has been observed in individual(s) with nonsyndromic deafness (PMID: 32048449). ClinVar contains an entry for this variant (Variation ID: 228704). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on 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. -
