Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4_StrongBP6
The NM_032119.4(ADGRV1):c.12181G>T(p.Val4061Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000971 in 1,611,492 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict 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. V4061L) has been classified as Uncertain significance.

Usher syndrome type 2C Uncertain:1Other:1
Variant interpreted as Uncertain significance and reported on 12-01-2020 by Invitae. GenomeConnect-Invitae Patient Insights Network assertions are reported exactly as they appear on the patient-provided report from the testing laboratory. Registry team members make no attempt to reinterpret the clinical significance of the variant. Phenotypic details are available under supporting information. -
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 Uncertain:1
Variant classified as Uncertain Significance - Favor Benign. The Val4061Phe vari ant in GPR98 has been previously reported in one individual with hearing loss by our laboratory; however, a second variant in GPR98 was not identified in this i ndividual. The Val4061Phe variant has been also been identified in 0.1% (14/8220 ) of European American chromosomes by the NHLBI Exome Sequencing Project (http:/ /evs.gs.washington.edu/EVS/; dbSNP rs200816323); however this frequency is not h igh enough to rule out pathogenicity. Computational analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide st rong support for or against an impact to the protein. In summary, the clinical s ignificance of this variant cannot be determined with certainty; however, based upon its frequency in the general population, we lean towards a more likely beni gn role. -
