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]

Collection Method:clinical testing

The p.Pro489Leu variant in GPR98 has not been previously reported in individuals with hearing loss, but has been identified in 2/111492 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org/; dbSN P rs371781264). Although this variant has been seen in the general population, i ts frequency is not high enough to rule out a pathogenic role. Computational pre diction tools and conservation analysis do not provide strong support for or aga inst an impact to the protein. In summary, the clinical significance of the p.Pr o489Leu variant is uncertain. -
