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]

RAD50 has been only recently described in association with cancer predisposition and the risks are not well understood. This variant is denoted RAD50 IVS19+5G>A, or c.3036+5G>A and consists of a G>A nucleotide substitution at the +5 position of intron 19 of the RAD50 gene. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD50 3036+5G>A occurs at a position that is well conserved throughout evolution. This particular nucleotide substitution was observed in multiple subpopulations, with the highest allele frequency of 0.09% (8/8588) in European Americans in the NHLBI Exome Sequencing Project. Multiple in silico splicing models predict a reduced likelihood that the nearby canonical donor splice site is utilized. At the molecular level, the impact of this missense variant on protein structure and function is not known and we consider this to be a variant of uncertain significance. Futhermore, based on the currently available information, cancer risks associated with this variant, and the RAD50 gene, remain unclear. -

Review Status:criteria provided, single submitter

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Variant summary: The RAD50 c.3036+5G>A variant involves the alteration of a non-conserved intronic nucleotide. One in silico tool predicts a polymorphism outcome for this variant. 5/5 splice prediction tools predict a weakening effect on the canonical splicing donor site and 3/5 predict loss of a cryptic splicing donor site at the nucleotide of interest. However, these predictions have yet to be confirmed by functional studies. This variant was found in 352/276630 control chromosomes, predominantly observed in the Ashkenazi Jewish subpopulation at a frequency of 0.013132 (133/10128). This frequency is about 210 times the estimated maximal expected allele frequency of a pathogenic RAD50 variant (0.0000625), suggesting this is likely a benign polymorphism found primarily in the populations of Ashkenazi Jewish origin. This variant has been reported in affected individuals without strong evidence for causality. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign/VUS, all without evidence for independent evaluation. Taken together, this variant is currently classified as likely benign. -
