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.Trp4962X variant in GPR98 has not been previously reported in individuals with hearing loss or Usher syndrome and was absent from large population studies .This nonsense variant leads to a premature termination codon at position 4962, which is predicted to lead to a truncated or absent protein. Loss of function of the GPR98 gene is an established disease mechanism in autosomal recessive Usher syndrome. In summary, this variant meets our criteria to be classified as patho genic for Usher syndrome in an autosomal recessive manner based on the predicted impact of the variant. -
