Variant summary: MRE11A c.391G>A (p.Asp131Asn) results in a conservative amino acid change located in the Calcineurin-like phosphoesterase domain, ApaH type of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.7e-05 in 275990 control chromosomes. This frequency is not higher than expected for a pathogenic variant in MRE11A causing Hereditary Breast and Ovarian Cancer (4.7e-05 vs 6.3e-05), allowing no conclusion about variant significance. c.391G>A has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer. These reports do not provide unequivocal conclusions about an 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. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.
