| Ambry Genetics | RCV000166766 | SCV000217579 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-09-05 | criteria provided, single submitter | clinical testing | The p.M779T variant (also known as c.2336T>C), located in coding exon 14 of the RAD50 gene, results from a T to C substitution at nucleotide position 2336. The methionine at codon 779 is replaced by threonine, an amino acid with 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. |
| Invitae | RCV000166766 | SCV000753355 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-12-08 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 779 of the RAD50 protein (p.Met779Thr). This variant is present in population databases (rs760464146, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. ClinVar contains an entry for this variant (Variation ID: 187078). 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. |
