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.K398E variant (also known as c.1192A>G), located in coding exon 8 of the RAD50 gene, results from an A to G substitution at nucleotide position 1192. The lysine at codon 398 is replaced by glutamic acid, an amino acid with similar properties. 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 lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 398 of the RAD50 protein (p.Lys398Glu). This variant is present in population databases (rs756173890, gnomAD 0.02%). 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: 219813). 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. 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: no assertion criteria provided

Collection Method: clinical testing

The RAD50 c.1192A>G variant is predicted to result in the amino acid substitution p.Lys398Glu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.019% of alleles in individuals of European (Non-Finnish) descent in gnomAD and is interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/219813/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
