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 c.1211A>G at the cDNA level, p.Gln404Arg (Q404R) at the protein level, and results in the change of a Glutamine to an Arginine (CAA>CGA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD50 Gln404Arg was not observed at a significant allele frequency in 1000 Genomes, and was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This variant is a semi-conservative substitution in which a neutral polar amino acid is replaced with a positive polar one, altering a position that is moderately conserved throughout evolution and is located within a potential coiled coil region (UniProt). In silico analyses predict this variant to have a benign effect on protein structure and function. On a molecular level, the impact of this missense variant on protein structure and function is not known and thus we consider this to be a variant of uncertain significance. Furthermore, based on the currently available information, cancer risks associated with this variant, and the RAD50 gene, remain unclear. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

DNA sequence analysis of the RAD50 gene demonstrated a sequence change, c.1211A>G, in exon 8 that results in an amino acid change, p.Gln404Arg. This sequence change does not appear to have been previously described in patients with RAD50-related disorders and has been described in the gnomAD database with a low population frequency of 0.16% in East Asian subpopulation (dbSNP rs200017020). The p.Gln404Arg change affects a moderately conserved amino acid residue located in a domain of the RAD50 protein that is known to be functional. The p.Gln404Arg substitution appears to be benign using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL).Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Gln404Arg change remains unknown at this time. -
