Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_005732.4(RAD50):c.871G>A(p.Glu291Lys) variant causes a missense change. The variant allele was found at a frequency of 0.00000868 in 1,613,582 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 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. E291D) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 291 of the RAD50 protein (p.Glu291Lys). This variant is present in population databases (rs375069351, gnomAD 0.01%). 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: 186705). 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) 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. -
The p.E291K variant (also known as c.871G>A), located in coding exon 6 of the RAD50 gene, results from a G to A substitution at nucleotide position 871. The glutamic acid at codon 291 is replaced by lysine, an amino acid with similar properties. This amino acid position is poorly 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. -
