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.Met6001Leu variant in GPR98 has not been previously reported in individual s with hearing loss or Usher syndrome. This variant has been identified in 7/61 554 European and 2/9336 African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs200530343); however, its frequenc y is not high enough to rule out a pathogenic role. Computational prediction too ls and conservation analysis do not provide strong support for or against an imp act to the protein. In summary, the clinical significance of the p.Met6001Leu va riant is uncertain.

Collection Method:clinical testing

The c.18001A>T (p.M6001L) alteration is located in exon 85 (coding exon 85) of the ADGRV1 gene. This alteration results from a A to T substitution at nucleotide position 18001, causing the methionine (M) at amino acid position 6001 to be replaced by a leucine (L). 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 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.

Significance:Uncertain significance
Review Status:no assertion criteria provided
Collection Method:clinical testing

The ADGRV1 c.18001A>T variant is predicted to result in the amino acid substitution p.Met6001Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.013% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
