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 c.3813_3815delAGA variant (also known as p.E1271del) is located in coding exon 25 of the RAD50 gene. This variant results from an in-frame AGA deletion at nucleotide positions 3813 to 3815. This results in the in-frame deletion of a glutamic acid at codon 1271. This amino acid position is highly conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Collection Method:clinical testing

This variant, c.3813_3815del, results in the deletion of 1 amino acid(s) of the RAD50 protein (p.Glu1271del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs776601293, gnomAD 0.02%). This variant has been observed in individual(s) with pancreatic cancer (PMID: 27732944, 27783279). ClinVar contains an entry for this variant (Variation ID: 482096). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
