Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBP6

The NM_032119.4(ADGRV1):​c.2759G>A​(p.Arg920Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000249 in 1,609,334 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R920R) has been classified as Likely benign.

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.Arg920Gln in exon 15 of GPR98: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, five mammals have a glutamine (Gln) at this position despite high nearby a mino acid conservation. It has been identified in 2/125856 European chromosomes, 1/29848 South Asian chromosomes, and 1/33630 Latino chromosomes by the Genome A ggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs766225545 ). -
