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

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The ADGRV1 c.16312A>G variant is predicted to result in the amino acid substitution p.Thr5438Ala. This variant was reported in an individual with uveitis (Table S2, Li et al. 2020. PubMed ID: 32707200) and in a patient with Usher syndrome (Table S3, Le Quesne Stabej et al. 2011. PubMed ID: 22135276). This variant is reported in 0.079% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Thr5438Ala in Exon 76 of GPR98: This variant is not expected to have clinical si gnificance because it is poorly conserved across species, with two primates (mar moset and squirrel monkey) having an Ala at this position, and computational too ls (amino acid conservation, AlignGVGD, PolyPhen2, and SIFT) do not suggest an i mpact to the protein. In addition, it has been previously reported in one study as a "neutral" variant due to its presence in 4/878 (0.48%) control chromosomes (Le Quesne Stabej 2012), and was also identified in 0.1% (5/8240) of European A merican chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washing ton.edu; dbSNP rs201890097). -
