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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Leu3809His variant in GPR98 has not been previously reported in individual s with hearing loss or Usher syndrome, or in large population studies. Computati onal prediction tools and conservation analysis suggest that the p.Leu3809His va riant may not impact the protein, though this information is not predictive enou gh to rule out pathogenicity. In summary, the clinical significance of the p.Leu 3809His variant is uncertain. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.11426T>A (p.L3809H) alteration is located in exon 55 (coding exon 55) of the ADGRV1 gene. This alteration results from a T to A substitution at nucleotide position 11426, causing the leucine (L) at amino acid position 3809 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces leucine, which is neutral and non-polar, with histidine, which is basic and polar, at codon 3809 of the ADGRV1 protein (p.Leu3809His). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ADGRV1-related conditions. ClinVar contains an entry for this variant (Variation ID: 505875). 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) performed at Invitae indicates that this missense variant is not expected to disrupt ADGRV1 protein function with a negative predictive value of 95%. 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. -
