Ambry Genetics | RCV000566036 | SCV000666412 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-01-18 | criteria provided, single submitter | clinical testing | The p.S681W variant (also known as c.2042C>G), located in coding exon 18 of the MRE11A gene, results from a C to G substitution at nucleotide position 2042. The serine at codon 681 is replaced by tryptophan, an amino acid with highly dissimilar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
Invitae | RCV001062032 | SCV001226801 | uncertain significance | Ataxia-telangiectasia-like disorder | 2022-07-17 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with tryptophan, which is neutral and slightly polar, at codon 681 of the MRE11 protein (p.Ser681Trp). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with MRE11-related conditions. ClinVar contains an entry for this variant (Variation ID: 481751). 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 C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. |
