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]

This sequence change creates a premature translational stop signal (p.Arg4211*) 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 (rs727504777, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with deafness (PMID: 33724713). ClinVar contains an entry for this variant (Variation ID: 179305). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -

The Arg4211X variant in GPR98 has not been reported in individuals with hearing loss or in large population studies. This nonsense variant leads to a premature termination codon at position 4211, which is predicted to lead to a truncated or absent protein. In summary, this variant meets our criteria to be classified as pathogenic (http://pcpgm.partners.org/LMM). -
