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]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.815

Variant summary: ADGRV1 c.1093G>T (p.Asp365Tyr) results in a non-conservative amino acid change located in the Na-Ca exchanger/integrin-beta4 domain of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 249118 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1093G>T in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 522916). Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 365 of the ADGRV1 protein (p.Asp365Tyr). This variant is present in population databases (rs372147148, gnomAD no frequency). 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: 522916). 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: "Benign"; Align-GVGD: "Class C25"). 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. -
