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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jun 14, 2022	This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 4640 of the ADGRV1 protein (p.Gly4640Glu). This variant is present in population databases (rs727504706, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with ADGRV1-related conditions. ClinVar contains an entry for this variant (Variation ID: 179204). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Variant classified as Uncertain Significance - Favor Benign. The p.Gly4640Glu va riant in GPR8 has been previously reported in one individual with Usher syndrome (Le Quesne Stabej 2012) and was identified by our laboratory in three individua ls with hearing loss; however, this variant was not thought to be related to the clinical features in these individuals due to the presence of an alternate expl anation of the hearing loss and/or non-segregation with disease in affected fami ly members. Data from large population studies are insufficient to assess the fr equency of this variant. Computational prediction tools and conservation analysi s suggest that the p.Gly4640Glu variant may impact the protein, though this info rmation is not predictive enough to determine pathogenicity. In summary, the cli nical significance of the p.Gly4640Glu variant is uncertain; however, based on t he identification of this variant in several individuals with an alternate expla nation for their hearing loss suggests that it is more likely to be benign. -
