Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBP6
The NM_005591.4(MRE11):c.2042C>T(p.Ser681Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000198 in 1,613,558 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S681W) has been classified as Uncertain significance.

Ataxia-telangiectasia-like disorder 1 Uncertain:2

This submission and the accompanying classification are no longer maintained by the submitter. For more information on current observations and classification, please contact variantquestions@myriad.com. -
not provided Uncertain:1
Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Observed in at least one individual with a personal and/or family history of breast cancer; however, no additional information was provided (Yadav et al., 2017); This variant is associated with the following publications: (PMID: 27878467) -
Ataxia-telangiectasia-like disorder Uncertain:1
This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 681 of the MRE11 protein (p.Ser681Leu). This variant is present in population databases (rs587782166, gnomAD 0.002%). This missense change has been observed in individual(s) with a personal or family history of breast and ovarian cancer (PMID: 27878467). ClinVar contains an entry for this variant (Variation ID: 141995). 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 tolerated. 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. -
Hereditary cancer-predisposing syndrome Benign:1
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. -
