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]

Submissions by phenotype

not provided Uncertain:3
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 24, 2021This sequence change affects codon 1459 of the ADGRV1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the ADGRV1 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs745380273, gnomAD 0.008%). 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: 376997). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
