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]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 03, 2024	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1260 of the RAD50 protein (p.Arg1260His). This variant is present in population databases (rs367683141, gnomAD 0.03%). This missense change has been observed in individual(s) with RAD50-related conditions (PMID: 31159747). ClinVar contains an entry for this variant (Variation ID: 142065). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RAD50 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 09, 2022	The p.R1260H variant (also known as c.3779G>A), located in coding exon 25 of the RAD50 gene, results from a G to A substitution at nucleotide position 3779. The arginine at codon 1260 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

In the published literature, the variant has been reported in an individual with personal and/or family history of breast and/or ovarian cancer (PMID: 31159747 (2019), 32658311 (2021)). In a large-scale breast cancer association study, the variant was observed in individuals with breast cancer as well as in unaffected individuals (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/RAD50)).The frequency of this variant in the general population, 0.00034 (12/35436 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -
