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, criteria provided, single submitter	clinical testing	Invitae	Oct 28, 2022	This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 6259 of the ADGRV1 protein (p.Asp6259Tyr). This variant is present in population databases (rs397517428, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with ADGRV1-related conditions. ClinVar contains an entry for this variant (Variation ID: 46302). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Dec 23, 2022	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; In silico analysis is inconclusive as to whether the variant alters gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; Has not been previously published as pathogenic or benign to our knowledge -

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Aug 17, 2010

The Asp6259Tyr variant in GPR98 has not been reported in the literature nor prev iously identified by our laboratory. This residue is conserved across many speci es and computational analyses (PolyPhen, SIFT) suggest that the Asp6259Tyr varia nt may impact the protein. However, this information is not predictive enough to assume pathogenicity. In addition, this individual's racial background is repor ted to be Hispanic. It should be noted that this laboratory has only tested 11 H ispanic probands and therefore has limited data on the spectrum of benign varian ts in this population. Future analysis could reveal that the Asp6259Tyr variant is common in this population and therefore unlikely to be disease causing. In su mmary, the clinical significance of this variant cannot be determined at this ti me. -
