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.2288G>A at the cDNA level, p.Arg763His (R763H) at the protein level, and results in the change of an Arginine to a Histidine (CGC>CAC). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD50 Arg763His was not observed at significant allele frequency in the NHLBI Exome Sequencing Project. This variant is a conservative substitution of one positive polar amino acid for another, altering a position that is well conserved throughout evolution and is not located in a known functional domain. 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. -

Significance: Likely benign
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. -

Variant summary: RAD50 c.2288G>A (p.Arg763His) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00033 in 250948 control chromosomes, predominantly at a frequency of 0.00058 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 9.28 fold of the estimated maximal expected allele frequency for a pathogenic variant in RAD50 causing Hereditary Breast And Ovarian Cancer Syndrome phenotype (6.3e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. c.2288G>A has been reported in the literature in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome without strong evidence for causality (Bono_2021, Damiola_2014). These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. ClinVar contains an entry for this variant (Variation ID: 128003). Based on the evidence outlined above, the variant was classified as likely benign. -
