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]

Variant summary: ADGRV1 c.8651T>C (p.Val2884Ala) results in a non-conservative amino acid change located in the Na-Ca exchanger/integrin-beta4 domain (IPR003644) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 6e-05 in 248472 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in ADGRV1 causing Usher Syndrome (6e-05 vs 0.0054), allowing no conclusion about variant significance. c.8651T>C has been reported in the literature in at least one individual with a clinical diagnosis of Usher syndrome (Sloan-Heggen_2016). The data does not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.

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 ADGRV1 c.8651T>C variant is predicted to result in the amino acid substitution p.Val2884Ala. This variant was reported in patient with Usher syndrome and no second variant (Table S3, Sloan-Heggen et al. 2016. PubMed ID: 26969326). This variant is reported in 0.017% of alleles in individuals of African descent in gnomAD. This variant is interpreted as no interpretation set.
