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 ADGRV1 c.9643G>A:p.(Glu3215Lys) heterozygous variant is very rare and predicted deleterious. This variant was classified as likely pathogenic by Deafness Variation Database, and according to ClinVar SCV000063351.5, it was detected in hearing impaired individuals. In our study, it was detected in an individual with sloping normal-to-severe HL, that carried another variant in USH1G,c.955A>G:p.(Arg319Gly), suggesting digenic inheritance. -

The p.Glu3215Lys variant in ADGRV1 has been previously reported by our laborator y in 2 individuals with hearing loss, one of whom also harbored a second ADGRV1 variant of uncertain significance (trans/cis not yet determined). The variant wa s also identified in 51/126478 European chromosomes by the Genome Aggregation Da tabase (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs199499672). However, t his frequency is not high enough to rule out a pathogenic role. Computational pr ediction tools and conservation analysis suggest that this variant may impact th e protein, though this information is not predictive enough to determine pathoge nicity. In summary, the clinical significance of the p.Glu32215Lys variant is un certain. ACMG/AMP Criteria applied: PP3. -
