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 c.1300_1306delGATAAGA pathogenic mutation, located in coding exon 9 of the RAD50 gene, results from a deletion of 7 nucleotides at nucleotide positions 1300 to 1306, causing a translational frameshift with a predicted alternate stop codon (p.D434Kfs*7). 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 variant has not been reported in the literature in individuals affected with RAD50-related conditions. This sequence change creates a premature translational stop signal (p.Asp434Lysfs*7) 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 (rs774833591, gnomAD 0.0009%). ClinVar contains an entry for this variant (Variation ID: 230850). For these reasons, this variant has been classified as Pathogenic. -
