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]

LUCAT1 (HGNC:48498): (lung cancer associated transcript 1)

LOC107986432 (HGNC:):

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Tyr6244*) 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 (rs761560344, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with Usher syndrome (PMID: 14740321). ClinVar contains an entry for this variant (Variation ID: 6801). For these reasons, this variant has been classified as Pathogenic. -

Observed in four siblings with clinical features of Usher syndrome type 2, however a second variant in ADGRV1 was not identified (PMID: 14740321); Nonsense variant predicted to result in protein truncation, as the last 63 amino acids are lost, and other loss-of-function variants have been reported downstream in HGMD; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 14740321) -
