Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4_StrongBP6
The NM_032119.4(ADGRV1):c.6994A>T(p.Ile2332Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000279 in 1,611,626 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). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I2332T) has been classified as Likely benign.

The ADGRV1 p.Ile2332Phe variant (rs193030567) was reported in one individual with a diagnosis of Usher syndrome type 2C who also harbored the p.Val617Met variant (Sloan-Heggen 2016). The p.Ile2332Phe 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 10,072 chromosomes) and has been reported to the ClinVar database (Variation ID: 46359). The isoleucine at position 2332 is highly conserved considering 12 species up to zebrafish (Alamut software v2.10.0), and computational analyses predict that this variant does affect the structure/function of the ADGRV1 protein (SIFT: damaging, MutationTaster: disease causing, PolyPhen-2: possibly damaging). Altogether, there is not enough evidence to classify the p.Ile2332Phe 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.Ile2332Phe in exon 32 of GPR98: This variant is not expected to have clinical significance because it has been identified in 0.3% (28/10072) of Ashkenazi Jewi sh chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadin stitute.org; dbSNP rs193030567). -
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). -
