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]

Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.R278* pathogenic mutation (also known as c.832C>T), located in coding exon 6 of the RAD50 gene, results from a C to T substitution at nucleotide position 832. This changes the amino acid from an arginine to a stop codon within coding exon 6. This mutation has been detected in 1/1824 patients with triple negative breast cancer who were unselected for a family history of breast or ovarian cancer (Couch FJ et al. J. Clin. Oncol. 2015 Feb;33:304-11) as well as 1/615 unselected patients with a pancreatic exocrine neoplasm (Lower MA et al. J. Natl. Cancer Inst. 2018 Oct;110(10):1067-1074). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -

Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Arg278*) in the RAD50 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RAD50 are known to be pathogenic (PMID: 19409520). This variant is present in population databases (rs766315644, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with breast cancer (PMID: 25452441). ClinVar contains an entry for this variant (Variation ID: 408402). For these reasons, this variant has been classified as Pathogenic. -

Significance: Pathogenic
Review Status: no assertion criteria provided
Collection Method: clinical testing

The RAD50 c.832C>T variant is predicted to result in premature protein termination (p.Arg278*). This variant has been reported in individuals with breast cancer (Table S2, Couch et al. 2015. PubMed ID: 25452441), ovarian cancer (Table S7, Lilyquist et al. 2017. PubMed ID: 28888541), exocrine pancreatic neoplasm (Lowery et al. 2018. PubMed ID: 29506128), and an individual with prostate cancer (Table S1, Nguyen-Dumont et al. 2020. PubMed ID: 32338768). This variant is reported in 0.012% of alleles in individuals of Latino descent in gnomAD and is interpreted as pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/408402/). Nonsense variants in RAD50 are expected to be pathogenic. This variant is interpreted as pathogenic. -
