RCV000497527 | SCV000590064 | uncertain significance | not provided | 2017-06-05 | criteria provided, single submitter | clinical testing | The P4181L variant in the ADGRV1 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The P4181L variant is observed in 3/14198 (0.021%) alleles from individuals of South Asian background, in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The P4181L variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret P4181L as a variant of uncertain significance. |

RCV001157421 | SCV001318989 | uncertain significance | Usher syndrome type 2C | 2018-01-13 | criteria provided, single submitter | 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. |

RCV001195218 | SCV001365525 | uncertain significance | not specified | 2019-11-26 | criteria provided, single submitter | clinical testing | The p.Pro4181Leu variant in ADGRV1 has not been previously reported in individuals with hearing loss but has been identified in 0.01% (6/30336) of South Asian chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant has also been reported in ClinVar (Variation ID 432348). Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of this variant is uncertain. ACMG/AMP Criteria applied: PM2_Supporting. |
