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]

Variant classified as Uncertain Significance - Favor Benign. The p.Asp4832Glu va riant in ADGRV1 has not been previously reported in individuals with Usher syndr ome, but has been identified in 4/24110 of South Asian chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs7538036 15). Although this variant has been seen in the general population, its frequenc y is not high enough to rule out a pathogenic role. Computational prediction too ls and conservation analyses suggest that this variant may not impact the protei n, though this information is not predictive enough to rule out pathogenicity. I n summary, while the clinical significance of the p.Asp4832Glu variant is uncert ain, the variant is more likely to be benign. ACMG/AMP Criteria applied: BP4 -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.14496C>A (p.D4832E) alteration is located in exon 70 (coding exon 70) of the ADGRV1 gene. This alteration results from a C to A substitution at nucleotide position 14496, causing the aspartic acid (D) at amino acid position 4832 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
