Hereditary cancer-predisposing syndrome Uncertain:2
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1166 of the RAD50 protein (p.Arg1166Gln). This variant is present in population databases (rs763145238, gnomAD 0.003%). 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: 484631). Invitae Evidence 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 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. 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. -
The p.R1166Q variant (also known as c.3497G>A), located in coding exon 23 of the RAD50 gene, results from a G to A substitution at nucleotide position 3497. The arginine at codon 1166 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
