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]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.D946V variant (also known as c.2837A>T), located in coding exon 18 of the RAD50 gene, results from an A to T substitution at nucleotide position 2837. The aspartic acid at codon 946 is replaced by valine, an amino acid with highly dissimilar properties. This variant was reported in 1/1313 early-onset breast cancer cases and 0/1123 population controls (Damiola F et al. Breast Cancer Res. 2014 Jun;16:R58). Another study identified this variant in one individual from a cohort of breast cancer probands who underwent multi-gene panel testing (Young EL et al. J. Med. Genet. 2016 06;53(6):366-76). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 946 of the RAD50 protein (p.Asp946Val). This variant is present in population databases (rs587782311, gnomAD 0.007%). This missense change has been observed in individual(s) with breast cancer (PMID: 26787654). This missense change has been observed to co-occur in individuals with a different variant in RAD50 that has been determined to be pathogenic (internal data), but the significance of this finding is unclear. ClinVar contains an entry for this variant (Variation ID: 142213). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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.

RAD50-related disorder Uncertain:1

PreventionGenetics, part of Exact Sciences
Significance:Uncertain significance
Review Status:no assertion criteria provided
Collection Method:clinical testing

The RAD50 c.2837A>T variant is predicted to result in the amino acid substitution p.Asp946Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0066% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
