Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.
The NM_005591.4(MRE11):c.1462C>T(p.Arg488Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000675 in 1,613,930 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. R488G) has been classified as Uncertain significance.

Ataxia-telangiectasia-like disorder 1 Uncertain:3
MRE11 NM_005591.4 exon 13 p.Arg488Cys (c.1462C>T): This variant has been observed in individuals in at least 10 individuals undergoing genetic testing for hereditary cancer predisposition (Couch 2015 PMID:25452441; Tsaousis 2019 PMID:31159747). It is present in 0.02% (26/129120) European alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/11-94192612-G-A?dataset=gnomad_r2_1). This variant is present in ClinVar with classifications ranging from likely benign to VUS (Variation ID: 127972). Evolutionary conservation and computational predictive tools suggest that this variant may impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Hereditary cancer-predisposing syndrome Uncertain:1Benign: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. -

not provided Uncertain:1
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 36922933, 29641532, 26787654, 28569743, 25452441, 31159747, 31942411) -
Ataxia-telangiectasia-like disorder Uncertain:1
This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 488 of the MRE11 protein (p.Arg488Cys). This variant is present in population databases (rs375261439, gnomAD 0.02%). This missense change has been observed in individual(s) with breast cancer and in individuals undergoing genetic testing for hereditary cancer predisposition (PMID: 25452441, 31159747). ClinVar contains an entry for this variant (Variation ID: 127972). 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 disruptive. 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. -
