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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	research	Ocular Genomics Institute, Massachusetts Eye and Ear	Apr 08, 2021	The GPR98 c.14432C>A variant was identified in an individual with retinitis pigmentosa with a presumed recessive inheritance pattern. Through a review of available evidence we were able to apply the following criteria: PM2. Based on this evidence we have classified this variant as Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 13, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

The p.Pro4811Gln va riant in ADGRV1 has been previously reported by our laboratory in 2 individuals with hearing loss. It has also been reported in ClinVar (Variation ID 228712). T his variant has been identified in 0.05% (68/123974) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). Computational prediction tools and co nservation analysis suggest that the p.Pro4811Gln variant may not impact the pro tein, though this information is not predictive enough to rule out pathogenicity . In summary, the clinical significance of the p.Pro4811Gln variant is uncertai n. ACMG/AMP criteria applied: PM2_Supporting, BP4. -

The c.14432C>A (p.P4811Q) alteration is located in exon 70 (coding exon 70) of the ADGRV1 gene. This alteration results from a C to A substitution at nucleotide position 14432, causing the proline (P) at amino acid position 4811 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
