Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3
The NM_005591.4(MRE11):c.230A>T(p.Glu77Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000342 in 1,461,654 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E77D) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:1
The p.E77V variant (also known as c.230A>T), located in coding exon 3 of the MRE11A gene, results from an A to T substitution at nucleotide position 230. The glutamic acid at codon 77 is replaced by valine, an amino acid with dissimilar properties. 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
This sequence change replaces glutamic acid with valine at codon 77 of the MRE11A protein (p.Glu77Val). The glutamic acid residue is moderately conserved and there is a moderate physicochemical difference between glutamic acid and valine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a MRE11A-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance.
