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:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Tyr4266X variant in ADGRV1 (also known as GPR98) has been previously reported in two individuals with hearing loss by our laboratory. Both individuals were tested before the age of 5 years and were not reported to have any vision concerns. This variant has also been identified in 0.02% (6/30350) South Asian chromosomes by gnomAD (http://gnomad.broadinstitute.org). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. This nonsense variant leads to a premature termination codon at position 4266, which is predicted to lead to a truncated or absent protein. Loss of function of the ADGRV1 gene is an established disease mechanism in autosomal recessive Usher syndrome. In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive Usher syndrome. ACMG/AMP Criteria applied: PVS1, PM3_Supporting, PP1, PM2_Supporting. -

This sequence change creates a premature translational stop signal (p.Tyr4266*) in the ADGRV1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ADGRV1 are known to be pathogenic (PMID: 19357117, 22135276, 22147658, 26226137, 30718709, 31047384, 32467589). This variant is present in population databases (rs777309662, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with autosomal recessive ADGRV1-related conditions (PMID: 28041643, 32581362). ClinVar contains an entry for this variant (Variation ID: 438168). For these reasons, this variant has been classified as Pathogenic. -
