Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4
The NM_005732.4(RAD50):c.3049T>C(p.Trp1017Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000695 in 1,583,762 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 nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. W1017C) has been classified as Uncertain significance.

Submissions by phenotype
Hereditary cancer-predisposing syndrome Uncertain:2
This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 1017 of the RAD50 protein (p.Trp1017Arg). This variant is present in population databases (no rsID available, 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: 527369). 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 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.W1017R variant (also known as c.3049T>C), located in coding exon 20 of the RAD50 gene, results from a T to C substitution at nucleotide position 3049. The tryptophan at codon 1017 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Familial cancer of breast Uncertain:1
This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 1017 of the RAD50 protein (p.Trp1017Arg). This amino acid position is highly conserved ( PhyloP=6.9). This variant is present in population databases (no rsID available, 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: 527369). In addition, the in silico prediction for this alteration is inconclusive. 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. -
