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]

Labcorp Genetics (formerly Invitae), Labcorp
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 glutamic acid, which is acidic and polar, at codon 637 of the RAD50 protein (p.Asp637Glu). This variant is present in population databases (rs144749616, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. ClinVar contains an entry for this variant (Variation ID: 128000). 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. -

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

The p.D637E variant (also known as c.1911T>A), located in coding exon 12 of the RAD50 gene, results from a T to A substitution at nucleotide position 1911. The aspartic acid at codon 637 is replaced by glutamic acid, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Collection Method:clinical testing

Variant summary: RAD50 c.1911T>A (p.Asp637Glu) results in a conservative amino acid change located in the RAD50, zinc hook domain (IPR013134) of 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 5.6e-05 in 251332 control chromosomes, predominantly at a frequency of 0.00011 within the Non-Finnish European subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in RAD50 causing Nijmegen Breakage Syndrome-Like Disorder (5.6e-05 vs 0.0024), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.1911T>A in individuals affected with Nijmegen Breakage Syndrome-Like Disorder and no experimental evidence demonstrating its impact on protein function have been reported. The following publications have been ascertained in the context of this evaluation (PMID: 19917125, 26787654, 24894818, 28102005, 23555315, 24448499). ClinVar contains an entry for this variant (Variation ID: 128000). Based on the evidence outlined above, the variant was classified as uncertain significance. -

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

RAD50 has been only recently described in association with cancer predisposition and the risks are not well understood. This variant is denoted RAD50 c.1911T>A at the cDNA level, p.Asp637Glu (D637E) at the protein level, and results in the change of an Aspartic Acid to a Glutamic Acid (GAT>GAA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD50 Asp637Glu was not observed at a significant allele frequency in the NHLBI Exome Sequencing Project or 1000 Genomes. This variant is a conservative substitution of one negative polar amino acid for another, altering a position that is well conserved throughout evolution and is located in a potential coiled coil region in the Zinc-hook domain (UniProt). In silico analyses are inconsistent with regard to the effect this variant may have 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. -
