| Invitae | RCV001366781 | SCV001563096 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-09-08 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 768 of the RAD50 protein (p.Ile768Val). This variant is not present in population databases (gnomAD no frequency). 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. 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. ClinVar contains an entry for this variant (Variation ID: 1057734). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. |
| Ambry Genetics | RCV001366781 | SCV002734868 | uncertain significance | Hereditary cancer-predisposing syndrome | 2020-03-17 | criteria provided, single submitter | clinical testing | The p.I768V variant (also known as c.2302A>G), located in coding exon 14 of the RAD50 gene, results from an A to G substitution at nucleotide position 2302. The isoleucine at codon 768 is replaced by valine, an amino acid with highly similar properties. This amino acid position is not well 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. |
