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 significance, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The ADGRV1 p.Asp3992Asn variant was identified in 2 of 896 proband chromosomes (frequency: 0.002) from individuals or families with Usher syndrome (Eandi_2017_PMID:29142287; Bonnet_2016_PMID:27460420). The variant was also identified in dbSNP (ID: rs201386977), ClinVar (classified as a VUS by GeneDx, EGL Genetics, Athena Diagnostics, ARUP and Praxis fuer Humangenetik Tuebingen and as likely benign by Laboratory for Molecular Medicine) and LOVD 3.0. The variant was not identified in Cosmic. The variant was identified in control databases in 320 of 228350 chromosomes at a frequency of 0.001401 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Ashkenazi Jewish in 54 of 9380 chromosomes (freq: 0.005757), Latino in 60 of 28672 chromosomes (freq: 0.002093), Other in 11 of 6242 chromosomes (freq: 0.001762), European (non-Finnish) in 168 of 99320 chromosomes (freq: 0.001692), South Asian in 19 of 25506 chromosomes (freq: 0.000745), European (Finnish) in 5 of 22700 chromosomes (freq: 0.00022) and African in 3 of 20596 chromosomes (freq: 0.000146), while the variant was not observed in the East Asian population. The p.Asp3992 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

Apr 27, 2017

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
