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.Gln6042Arg variant in GPR98 has not been previously reported in individual s with hearing loss or Usher syndrome, but has been identified in 2/66584 Europe an chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinsti tute.org; dbSNP rs764963960). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Com putational prediction tools and conservation analysis suggest that the p.Gln6042 Arg variant may not impact the protein, though this information is not predictiv e enough to rule out pathogenicity. In summary, the clinical significance of the p.Gln6042Arg variant is uncertain. -
