Genes affected

RAD50 (HGNC:9816): (RAD50 double strand break repair protein) The protein encoded by this gene is highly similar to Saccharomyces cerevisiae Rad50, a protein involved in DNA double-strand break repair. This protein forms a complex with MRE11 and NBS1. The protein complex binds to DNA and displays numerous enzymatic activities that are required for nonhomologous joining of DNA ends. This protein, cooperating with its partners, is important for DNA double-strand break repair, cell cycle checkpoint activation, telomere maintenance, and meiotic recombination. Knockout studies of the mouse homolog suggest this gene is essential for cell growth and viability. Mutations in this gene are the cause of Nijmegen breakage syndrome-like disorder.[provided by RefSeq, Apr 2010]

KCCC/NGS Laboratory, Kuwait Cancer Control Center

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

variant of uncertain significance was detected in exon 13 of the RAD50 gene (c.2174G>A). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 725 of the RAD50 protein (p.Arg725Gln). This variant is present in population databases (rs372808845, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with RAD50‐related conditions.This amino acid position is mild conserved (PhyloP=3.4) . ClinVar contains an entry for this variant (Variation ID: 142934). this alteration is predicted to be tolerated by in silico analysis. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R725Q variant (also known as c.2174G>A), located in coding exon 13 of the RAD50 gene, results from a G to A substitution at nucleotide position 2174. The arginine at codon 725 is replaced by glutamine, an amino acid with highly similar properties. This alteration was reported in conjunction with a duplication of exons 22-24 in RAD50 in an individual who underwent panel testing for hereditary cancer (Truty R et al. Genet Med, 2019 01;21:114-123). 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. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 725 of the RAD50 protein (p.Arg725Gln). This variant is present in population databases (rs372808845, gnomAD 0.002%). 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: 142934). 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The RAD50 c.2174G>A (p.Arg725Gln) variant has been reported in the published literature along with a RAD50 copy number variant in an individual undergoing genetic testing (PMID: 29895855 (2019)). The frequency of this variant in the general population, 0.000012 (3/249270 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools (i.e., MutationTaster and PolyPhen-2) for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -
