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]

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2022The p.A171S variant (also known as c.511G>T), located in coding exon 4 of the RAD50 gene, results from a G to T substitution at nucleotide position 511. The alanine at codon 171 is replaced by serine, an amino acid with similar properties. This variant was reported in 1/1313 early-onset breast cancer cases and 0/1123 population controls (Damiola F et al, 2014 Jun;16:R58). This alteration was also identified in an individual diagnosed with breast cancer who had a family history of breast and/or ovarian cancer (Wang J et al. Cancer Med, 2019 05;8:2074-2084). 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. -
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 13, 2023This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 171 of the RAD50 protein (p.Ala171Ser). This variant is present in population databases (rs143483210, gnomAD 0.08%). This missense change has been observed in individual(s) with breast cancer (PMID: 24894818). ClinVar contains an entry for this variant (Variation ID: 142739). 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. -
