Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3
The NM_005732.4(RAD50):c.2372A>C(p.Asp791Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,598 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. D791G) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 791 of the RAD50 protein (p.Asp791Ala). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RAD50 protein function. ClinVar contains an entry for this variant (Variation ID: 457405). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. This variant is present in population databases (rs758031764, gnomAD 0.003%). -
The p.D791A variant (also known as c.2372A>C), located in coding exon 14 of the RAD50 gene, results from an A to C substitution at nucleotide position 2372. The aspartic acid at codon 791 is replaced by alanine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
