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]

Collection Method: clinical testing

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 38 of the RAD50 protein (p.Asn38Ser). This variant is present in population databases (rs750480943, gnomAD 0.003%). This missense change has been observed in individual(s) with breast cancer (PMID: 24894818, 30613976). ClinVar contains an entry for this variant (Variation ID: 230314). 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 expected to disrupt RAD50 protein function with a positive predictive value of 80%. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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.N38S variant (also known as c.113A>G), located in coding exon 1 of the RAD50 gene, results from an A to G substitution at nucleotide position 113. The asparagine at codon 38 is replaced by serine, an amino acid with highly similar properties. This variant was reported in 2/1313 early-onset breast cancer cases and 0/1123 population controls (Damiola F et al. Breast Cancer Res, 2014 Jun;16:R58). This variant was identified in 1 of 523 BRCA1/2 negative male breast cancer patients undergoing multigene panel testing (Rizzolo P et al. Int J Cancer, 2019 Jul;145:390-400). This alteration was reported in a study of 1297 cases of early-onset breast cancer and 1121 controls (Young EL et al. J Med Genet, 2016 Jun;53:366-76). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
