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:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1052-5A>T intronic variant results from an A to T substitution 5 nucleotides upstream from coding exon 8 in the RAD50 gene. This nucleotide position is poorly conserved in available vertebrate species. RNA studies have demonstrated that this alteration does not result in abnormal splicing in the set of samples tested (Ambry internal data). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
