Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4_StrongBP6

The NM_032119.4(ADGRV1):c.2459A>G(p.Asn820Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000129 in 1,613,628 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N820K) has been classified as Uncertain significance.

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]

p.Asn820Ser in exon 13 of GPR98: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, four mammals have a Serine (Ser) at this position. In addition, it has bee n identified in 24/9798 (0.24%) of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org;dbSNP rs144918959). -
