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]

Likely benign, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 31, 2024	- -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jun 21, 2018	The H4453R variant in the ADGRV1 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The H4453R variant is observed in 43/126528 (0.034%) alleles from individuals of non-Finnish background, in large population cohorts (Lek et al., 2016). The H4453R variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. In-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. We interpret H4453R as a variant of uncertain significance. -

The p.His4453Arg variant in ADGRV1 has not been previously reported in individuals with hearing loss or Usher syndrome, but has been identified in 0.03% (48/128280) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant has also been reported in ClinVar (Variation ID 426807). Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of this variant is uncertain. ACMG/AMP Criteria applied: PM2_Supporting. -
