This sequence change replaces aspartic acid with asparagine at codon 131 of the MRE11 protein (p.Asp131Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs368403414, ExAC 0.01%). This variant has been observed in individuals affected with breast and/or ovarian cancer (PMID: 26534844, 26898890). ClinVar contains an entry for this variant (Variation ID: 142063). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: Deleterious; PolyPhen-2: Possibly Damaging; Align-GVGD: Class C1). 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. 5
