Description

MRE11A has been only recently described in association with cancer predisposition and the risks are not well understood. This variant is denoted MRE11A c.1163G>A at the cDNA level, p.Arg388Gln (R388Q) at the protein level, and results in the change of an Arginine to a Glutamine (CGG>CAG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. MRE11A Arg388Gln was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This variant is a semi-conservative substitution in which a positive polar amino acid is replaced with a neutral polar one, altering a position that is well conserved throughout evolution and is not located in a known functional domain. In silico analyses are inconsistent with regard to the effect this variant may have on protein structure and function. On a molecular level, the impact of this missense variant on protein structure and function is not known and thus we consider this to be a variant of uncertain significance. Furthermore, based on the currently available information, cancer risks associated with this variant, and the MRE11A gene, remain unclear.

Description

To the best of our knowledge, the variant has not been reported in the published literature. The frequency of this variant in the general population, 0.00014 (5/34588 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant.
