Variant summary
Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2BP4_StrongBP6
The NM_032119.4(ADGRV1):c.1849G>A(p.Val617Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000262 in 1,587,524 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

The ADGRV1 p.Val617Met variant (rs199988872) was reported in one individual with a diagnosis of Usher syndrome type 2C who also harbored the ADGRV1 p.Ile2332Phe variant (Sloan-Heggen 2016). The p.Val617Met variant is listed in the Genome Aggregation Database (gnomAD) with an allele frequency of 0.3 percent in the Ashkenazi Jewish population (identified on 28 out of 10,044 chromosomes) and has been reported to the ClinVar database (Variation ID: 137500). The valine at position 617 is highly conserved considering 12 species up to zebrafish (Alamut software v2.10.0), and computational analyses predict conflicting effects of this variant on protein structure/function (SIFT: damaging, GVGD: class C0, PolyPhen-2: possibly damaging). Altogether, there is not enough evidence to classify the p.Val617Met variant with certainty. -

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. -
not specified Benign:1
p.Val617Met in exon 10 of GPR98: This variant is not expected to have clinical s ignificance because it has been identified in 0.3% (28/10044) of Ashkenazi Jewis h chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadins titute.org; dbSNP rs199988872). -
ADGRV1-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
