RCV000656867 | SCV000149828 | uncertain significance | not provided | 2021-01-06 | criteria provided, single submitter | clinical testing | In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in individuals with a personal or family history including breast, ovarian, and colorectal cancer (Castera 2014, Belhadj 2020); This variant is associated with the following publications: (PMID: 32449991, 24549055, 31159747) |
Ambry Genetics | RCV000115919 | SCV000183953 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-05-15 | criteria provided, single submitter | clinical testing | The p.A177T variant (also known as c.529G>A), located in coding exon 5 of the MRE11A gene, results from a G to A substitution at nucleotide position 529. The alanine at codon 177 is replaced by threonine, an amino acid with similar properties. This variant has been reported in studies of patients with triple negative breast cancer who were unselected for family history of breast or ovarian cancer, in BRCA1/2-negative patients with early-onset breast cancer, and in patients with familial breast cancer and other hereditary cancers (Couch FJ et al. J. Clin. Oncol. 2015 Feb;33:304-11; Maxwell KN et al. Genet. Med. 2015 Aug;17:630-8; Li J et al. J. Med. Genet. 2016 Jan;53:34-42; Tsaousis GN et al. BMC Cancer 2019 Jun;19(1):535). This variant was also identified in 1 of 523 BRCA1/2 negative male breast cancer patients undergoing multigene panel testing (Rizzolo P et al. Int J Cancer, 2019 Jul;145:390-400). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
Invitae | RCV000791435 | SCV000254867 | uncertain significance | Ataxia-telangiectasia-like disorder | 2022-10-13 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 177 of the MRE11 protein (p.Ala177Thr). This variant is present in population databases (rs142996063, gnomAD 0.2%), including at least one homozygous and/or hemizygous individual. This missense change has been observed in individual(s) with a personal and/or family history of breast or ovarian cancer (PMID: 24549055, 25452441, 26534844). ClinVar contains an entry for this variant (Variation ID: 127983). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest 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. |

RCV000400887 | SCV000374941 | uncertain significance | Ataxia-telangiectasia-like disorder 1 | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |
