Genes affected
MRE11 (HGNC:7230): (MRE11 homolog, double strand break repair nuclease) This gene encodes a nuclear protein involved in homologous recombination, telomere length maintenance, and DNA double-strand break repair. By itself, the protein has 3' to 5' exonuclease activity and endonuclease activity. The protein forms a complex with the RAD50 homolog; this complex is required for nonhomologous joining of DNA ends and possesses increased single-stranded DNA endonuclease and 3' to 5' exonuclease activities. In conjunction with a DNA ligase, this protein promotes the joining of noncomplementary ends in vitro using short homologies near the ends of the DNA fragments. This gene has a pseudogene on chromosome 3. Alternative splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 11, 2023The p.E499G variant (also known as c.1496A>G), located in coding exon 12 of the MRE11A gene, results from an A to G substitution at nucleotide position 1496. The glutamic acid at codon 499 is replaced by glycine, an amino acid with similar properties. This alteration was reported in individual from a cohort of 684 HBOC families undergoing multi-gene testing (Li J et al. J. Med. Genet. 2016 Jan;53:34-42). This amino acid position is well 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. -
Ataxia-telangiectasia-like disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 03, 2023This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 499 of the MRE11 protein (p.Glu499Gly). This variant is present in population databases (rs774145193, gnomAD 0.03%). This missense change has been observed in individual(s) with breast and/or ovarian cancer (PMID: 26534844). ClinVar contains an entry for this variant (Variation ID: 229851). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
