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]

Variant summary: RAD50 c.3902A>G (p.Lys1301Arg) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 6.7e-05 in 253702 control chromosomes, predominantly at a frequency of 0.0006 within the East Asian subpopulation in the gnomAD database. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 10 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 East Asian origin. c.3902A>G has been reported in the literature in individuals affected with breast cancer, colorectal cancer, or multiple colorectal polyps (examples: Damiola_2014, Li_2018, Wang_2019, Yao_2022, Hernandez_2022). These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. One co-occurrence with another pathogenic variant has been reported (BRCA2 c.6096dupT, p.Ile2033fs; Wang_2019), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 28102005, 24894818, 34716202, 29891727, 30982232, 22216297, 35186721, 26787654). Five submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 (VUS, n=2; Likely benign, n=1; Benign, n=2). Based on the evidence outlined above, the variant was classified as likely benign. -
