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]

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

MRE11 NM_005591.4 exon 13 p.Arg488Cys (c.1462C>T): This variant has been observed in individuals in at least 10 individuals undergoing genetic testing for hereditary cancer predisposition (Couch 2015 PMID:25452441; Tsaousis 2019 PMID:31159747). It is present in 0.02% (26/129120) European alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/11-94192612-G-A?dataset=gnomad_r2_1). This variant is present in ClinVar with classifications ranging from likely benign to VUS (Variation ID: 127972). Evolutionary conservation and computational predictive tools suggest that this variant may impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 36922933, 29641532, 26787654, 28569743, 25452441, 31159747, 31942411) -

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 488 of the MRE11 protein (p.Arg488Cys). This variant is present in population databases (rs375261439, gnomAD 0.02%). This missense change has been observed in individual(s) with breast cancer and in individuals undergoing genetic testing for hereditary cancer predisposition (PMID: 25452441, 31159747). ClinVar contains an entry for this variant (Variation ID: 127972). 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 disruptive. 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. -
