Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4
The NM_005732.4(RAD50):c.715G>C(p.Glu239Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000062 in 1,613,278 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. E239K) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
The p.E239Q variant (also known as c.715G>C), located in coding exon 5 of the RAD50 gene, results from a G to C substitution at nucleotide position 715. The glutamic acid at codon 239 is replaced by glutamine, an amino acid with highly similar properties. This variant was reported in 1/1313 early-onset breast cancer cases and 0/1123 population controls (Damiola F et al. Breast Cancer Res., 2014 Jun;16:R58). This amino acid position is 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.
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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 482084). 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). This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 239 of the RAD50 protein (p.Glu239Gln).
