Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 4P and 2B. PM1PM2BP4_Moderate
The NM_005732.4(RAD50):c.1456C>A(p.Arg486Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000658 in 152,056 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 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. R486H) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Uncertain:2
The p.R486S variant (also known as c.1456C>A), located in coding exon 10 of the RAD50 gene, results from a C to A substitution at nucleotide position 1456. The arginine at codon 486 is replaced by serine, an amino acid with dissimilar 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. -
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) performed at Invitae indicates that this missense variant is not expected to disrupt RAD50 protein function. ClinVar contains an entry for this variant (Variation ID: 582915). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 486 of the RAD50 protein (p.Arg486Ser). -
