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]

The p.R380H variant (also known as c.1139G>A), located in coding exon 10 of the MRE11A gene, results from a G to A substitution at nucleotide position 1139. The arginine at codon 380 is replaced by histidine, an amino acid with highly similar properties. This variant was reported in one individual from a familial prostate cancer cohort (Leongamornlert D et al. Br. J. Cancer. 2014 Mar; 110(6):1663-72). This alteration has also been reported in a cohort of BRCA1/2 mutation-negative women with familial breast cancer (Li J et al. J. Med. Genet., 2016 Jan;53:34-42). Additionally, this alteration was identified in an individual diagnosed with breast and/or cancer who did not have the known pathogenic alteration in BRCA1/2 identified in their family (Dominguez-Valentin M et al. Hered Cancer Clin Pract, 2018 Jan;16:4). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Variant summary: MRE11A c.1139G>A (p.Arg380His) results in a non-conservative amino acid change located in the Mre11, DNA-binding domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 3.2e-05 in 277040 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. The variant, c.1139G>A has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer (Dominguez-Valentin_2018, Li_2015, Leongamornlert_2014). These reports 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. Two 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 uncertain significance. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 380 of the MRE11 protein (p.Arg380His). This variant is present in population databases (rs587781646, gnomAD 0.01%). This missense change has been observed in individual(s) with prostate cancer or breast cancer (PMID: 24556621, 26534844, 29371908). ClinVar contains an entry for this variant (Variation ID: 141307). 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. -
