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]

In silico analysis suggests that this missense variant does not alter protein structure/function; Observed in individuals with breast cancer and present only in controls in a study of common variable immunodeficiency (CVID) (PMID: 26898890, 25452441, 20805886); This variant is associated with the following publications: (PMID: 25452441, 26898890, 25344691, 20805886, 38878505) -

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

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

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. -

Variant summary: MRE11A c.1480G>A (p.Glu494Lys) results in a conservative amino acid change located in the outside of any known domain or repeat of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The observed variant frequency of 0.00049 (136/277134 chrs) is approximately 8.083 fold of the estimated maximal expected allele frequency for a pathogenic variant in MRE11A causing Hereditary Breast and Ovarian Cancer phenotype (6.3e-05), strongly suggesting that the variant is benign. The c.1480G>A has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer. These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as benign. -
