Hereditary cancer-predisposing syndrome    Uncertain:1 
The p.G575D variant (also known as c.1724G>A), located in coding exon 14 of the MRE11A gene, results from a G to A substitution at nucleotide position 1724. The glycine at codon 575 is replaced by aspartic acid, an amino acid with similar properties. This alteration has been reported in individuals with a personal history of ovarian and colon cancer from a cohort of 1191 cancer index patients who underwent clinical evaluation and testing with multigene panels (Chan GHJ et al. Oncotarget, 2018 Jul;9:30649-30660). This amino acid position is highly 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 
This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 575 of the MRE11 protein (p.Gly575Asp). This variant is present in population databases (rs376555330, gnomAD 0.08%). This missense change has been observed in individual(s) with colon cancer (PMID: 30093976). ClinVar contains an entry for this variant (Variation ID: 220769). 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. -
