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 submitterclinical testingAmbry GeneticsAug 11, 2022The p.R1093* pathogenic mutation (also known as c.3277C>T), located in coding exon 21 of the RAD50 gene, results from a C to T substitution at nucleotide position 3277. This changes the amino acid from an arginine to a stop codon within coding exon 21. This alteration was previously reported in the compound heterozygous state in a patient with a phenotype similar to Nijmegen breakage syndrome. Sequence analysis of cDNA revealed quasi-hemizygous expression of the other mutation, implying that the p.R1093* allele was subject to nonsense mediated decay (Waltes R et al. Am. J. Hum. Genet. 2009 May;84:605-16). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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 submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 22, 2023This sequence change creates a premature translational stop signal (p.Arg1093*) 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 (rs121912628, gnomAD 0.008%). This premature translational stop signal has been observed in individual(s) with medulloblastoma, and Nijmegen breakage syndrome-like disorder (PMID: 19409520). ClinVar contains an entry for this variant (Variation ID: 5872). For these reasons, this variant has been classified as Pathogenic. -
