Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_005732.4(RAD50):c.3293G>A(p.Arg1098Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,613,756 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1098W) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 05, 2022 | The p.R1098Q variant (also known as c.3293G>A), located in coding exon 21 of the RAD50 gene, results from a G to A substitution at nucleotide position 3293. The arginine at codon 1098 is replaced by glutamine, 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 10, 2023 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1098 of the RAD50 protein (p.Arg1098Gln). This variant is present in population databases (no rsID available, gnomAD 0.006%). 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: 220536). 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. 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. - |
