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]

This alteration is classified as 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.671G>A (p.Arg224His) results in a non-conservative amino acid change located in the AAA domain (IPR038729) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0007 in 395844 control chromosomes in the gnomAD database (v2.1 and v3.1 datasets), including 1 homozygote. The observed variant frequency is approximately 11-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 benign. The variant, c.671G>A, has been reported in the literature in individuals affected with breast or ovarian cancer, and other tumor phenotypes (e.g. Heikkinen_2003, Tommiska_2006, Damiola_2014, Lhota_2016, Hu_2016, Young_2016). However, in a recent large study evaluating breast cancer cases and controls in the Breast Cancer Association Consortium (BCAC), the variant was reported in 130/60466 cases and 107/53461 controls, suggesting no increased risk association for the variant with the disease (Dorling_2021 through LOVD). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and classified the variant as VUS (n=1), likely benign (n=2) / benign (n=1). Based on the evidence outlined above, the variant was classified as benign. -
