Ambry Genetics | RCV000164991 | SCV000215685 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-12-16 | criteria provided, single submitter | clinical testing | The p.V683I variant (also known as c.2047G>A), located in coding exon 13 of the RAD50 gene, results from a G to A substitution at nucleotide position 2047. The valine at codon 683 is replaced by isoleucine, an amino acid with highly similar properties. This variant was reported in 1/1313 early-onset breast cancer cases and 0/1123 population controls (Damiola F et al. Breast Cancer Res. 2014 Jun;16:R58). It was also reported in a study of 1297 cases of early-onset breast cancer and 1121 controls (Young EL et al. J. Med. Genet. 2016 Jun;53:366-76). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV000164991 | SCV000262064 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-05-06 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 683 of the RAD50 protein (p.Val683Ile). This variant is present in population databases (rs367925756, gnomAD 0.01%). This missense change has been observed in individual(s) with breast cancer (PMID: 24894818). ClinVar contains an entry for this variant (Variation ID: 185548). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RAD50 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |

Quest Diagnostics Nichols Institute San Juan Capistrano | RCV004998328 | SCV005625130 | uncertain significance | not provided | 2024-05-09 | criteria provided, single submitter | clinical testing | The RAD50 c.2047G>A (p.Val683Ile) variant has been reported in the published literature in an early onset breast cancer (PMID: 24894818 (2014)), as well as in breast cancer cases and reportedly healthy individuals in a large scale breast cancer association study (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/RAD50)). The frequency of this variant in the general population, 0.00035 (4/11496 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. |
