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]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 06, 2023	This sequence change creates a premature translational stop signal (p.Thr32Asnfs*16) 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 (rs587781625, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. ClinVar contains an entry for this variant (Variation ID: 141279). For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Sep 17, 2013	The c.94dupA pathogenic mutation, located in coding exon 1 of the RAD50 gene, results from a duplication of one nucleotide at position 94, causing a translational frameshift with a predicted alternate stop codon. Since frameshifts are typically deleterious in nature, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294). -

The RAD50 c.94dupA variant is predicted to result in a frameshift and premature protein termination (p.Thr32Asnfs*16). This variant has been reported in large population studies and carrier testing screens, where the phenotype of individuals is not known (LaDuca et al. 2017. PubMed ID: 28152038; Capalbo et al. 2019. PubMed ID: 31589614). This variant is reported in 0.0040% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/5-131893109-T-TA). Frameshift variants in RAD50 are expected to be pathogenic and this variant has been classified as pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/141279/). This variant is interpreted as likely pathogenic. -
