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

This variant is a duplication of 1 nucleotide in exon 13 of RAD50 mRNA (c.2165dupA). causing a frameshift at codon 723. This creates a premature translational stop signal (p.Glu723Glyfs*5) and is expected to result in an absent or disrupted protein product. Truncating mutations in RAD50 are known to be pathogenic. The mutation database ClinVar contains an entry for this variant (Variation ID: 37377/). -

Ambry Genetics

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2165dupA pathogenic mutation, located in coding exon 13 of the RAD50 gene, results from a duplication of A at nucleotide position 2165, causing a translational frameshift with a predicted alternate stop codon (p.E723Gfs*5). This alteration has been reported multiple individuals diagnosed with breast or prostate cancer (Lin PH et al. Oncotarget. 2016 Feb;7:8310-20; Fan C et al. Int J Cancer, 2018 10;143:1935-1942; Goidescu IG et al. Clujul Med, 2018 Apr;91:157-165; Wang YA et al. BMC Cancer, 2018 03;18:315; Matejcic M et al. JCO Precis Oncol, 2020 Jan;4:32-43). This alteration was also identified in trans with c.3109_3111del in an individual with bone marrow failure, microcephaly, skin pigmentation, nail dysplasia, dental loss and dysmorphia (Chansel-Da Cruz M et al. Cell Rep, 2020 12;33:108559). Of note, this alteration is also known as c.2157dupA in published literature. 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.Glu723Glyfs*5) 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). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with breast cancer (PMID: 25452441, 26824983). This variant is also known as c.2157dupA. ClinVar contains an entry for this variant (Variation ID: 141045). For these reasons, this variant has been classified as Pathogenic. -
