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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The p.Asn600Ser var iant in GPR98 has not been previously reported in individuals with hearing loss and was absent from large population studies. The asparagine (Asn) at position 6 00 is not conserved in mammals or evolutionary distant species, with Brush-taile d rat and two bird species having a serine (Ser), raising the possibility that a change at this position may be tolerated. Additional computational prediction t ools do not provide strong support for or against an impact to the protein. In s ummary, while the clinical significance of the Asn600Ser variant is uncertain, t he conservation data suggest that it is more likely to be benign. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1799A>G (p.N600S) alteration is located in exon 9 (coding exon 9) of the ADGRV1 gene. This alteration results from a A to G substitution at nucleotide position 1799, causing the asparagine (N) at amino acid position 600 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The ADGRV1 c.1799A>G variant is predicted to result in the amino acid substitution p.Asn600Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/5-89925316-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
