Ambry Genetics | RCV000572964 | SCV000667003 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-12-18 | criteria provided, single submitter | clinical testing | The p.L477R variant (also known as c.1430T>G), located in coding exon 9 of the RAD50 gene, results from a T to G substitution at nucleotide position 1430. The leucine at codon 477 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
Invitae | RCV000572964 | SCV001491704 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-09-12 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 477 of the RAD50 protein (p.Leu477Arg). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RAD50 protein function. ClinVar contains an entry for this variant (Variation ID: 482089). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. This variant is not present in population databases (gnomAD no frequency). |
