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.Val263Met variant in ADGRV1 has been previously reported by our laboratory in the heterozygous state in 1 individual with hearing loss; a variant affectin g the other copy of the gene was not identified. The Val263Met variant has also been identified in 7/34408 Latino chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs727505056). Although this va riant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation a nalyses do not provide strong support for or against an impact to the protein. I n summary, the clinical significance of the p.Val263Met variant is uncertain. A CMG/AMP Criteria applied: none. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.787G>A (p.V263M) alteration is located in exon 7 (coding exon 7) of the ADGRV1 gene. This alteration results from a G to A substitution at nucleotide position 787, causing the valine (V) at amino acid position 263 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
