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

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 28, 2023	The c.687delT pathogenic mutation, located in coding exon 5 of the RAD50 gene, results from a deletion of one nucleotide at nucleotide position 687, causing a translational frameshift with a predicted alternate stop codon (p.S229Rfs*6). This alteration was first reported in 2/151 Finnish familial breast/ovarian cancer individuals as well as in 6/1000 cancer free controls (Heikkinen K, J. Med. Genet. 2003 Dec; 40(12):e131). In a case control study of 317 consecutive newly diagnosed Finnish breast cancer patients and 1000 geographically matched healthy controls, eight breast cancer patients and six controls were carriers (95% CI 1.5–12.5, P = 0.008). Haplotype analysis suggests this is a Finnish founder mutation (Heikkinen K, Carcinogenesis 2006 Aug; 27(8):1). 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. -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Sep 14, 2023	Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this premature translational stop signal affects RAD50 function (PMID: 14684699, 16385572, 16474176). ClinVar contains an entry for this variant (Variation ID: 185010). This premature translational stop signal has been observed in individual(s) with hereditary breast and ovarian cancer in that population (PMID: 14684699, 16385572, 16474176, 25452441). It is commonly reported in individuals of Finnish ancestry (PMID: 14684699, 16385572, 16474176, 25452441). This variant is present in population databases (rs760146707, gnomAD 0.4%), and has an allele count higher than expected for a pathogenic variant. This sequence change creates a premature translational stop signal (p.Ser229Argfs*6) 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). -
