Ambry Genetics | RCV000164614 | SCV000215277 | likely benign | Hereditary cancer-predisposing syndrome | 2022-11-22 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: 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. |
Invitae | RCV000167992 | SCV000218642 | uncertain significance | Ataxia-telangiectasia syndrome | 2022-10-25 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 1361 of the ATM protein (p.Gln1361Arg). This variant is present in population databases (rs141921797, gnomAD 0.06%). This missense change has been observed in individual(s) with colon cancer or melanoma (PMID: 29684080, 34262154). ClinVar contains an entry for this variant (Variation ID: 185234). 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: "Benign"; Align-GVGD: "Class C0"). 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. |

RCV000164614 | SCV000682183 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-07-26 | criteria provided, single submitter | clinical testing | This missense variant replaces glutamine with arginine at codon 1361 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with melanoma (PMID: 34262154) and five carriers in a breast cancer case-control study, however the cancer status of the carriers were not specified (PMID: 31871109). This variant also has been reported in 9 individuals age 70 years or older without cancer (FLOSSIES; https://whi.color.com/variant/11-108158415-A-G). This variant has been identified in 17/280106 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |

RCV000780899 | SCV000918535 | uncertain significance | not specified | 2022-02-17 | criteria provided, single submitter | clinical testing | Variant summary: ATM c.4082A>G (p.Gln1361Arg) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.8e-05 in 248700 control chromosomes, predominantly at a frequency of 0.00062 within the African or African-American subpopulation in the gnomAD database. This frequency is not higher than expected for a pathogenic variant in ATM causing Breast Cancer (4.8e-05 vs 0.001), allowing no conclusion about variant significance. In addition, this variant has also been reported in 4/7325 European American and 5/2559 African American (i.e. with an allele frequency of 0.000977) women who were older than age 70 and cancer free (in the FLOSSIES database). The variant, c.4082A>G, has also been reported in the literature in cohorts of individuals affected with various tumor phenotypes, but without providing information on the associated phenotypes (examples: Haiman_2013, Yehia_2018, Adedokun_2020 and Dalmasso_2021). These reports therefore do not provide unequivocal conclusions about association of the variant with Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Nine clinical diagnostic laboratories have 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. |

RCV003153441 | SCV003843110 | uncertain significance | Familial cancer of breast | 2022-10-13 | criteria provided, single submitter | clinical testing | The ATM c.4082A>G (p.Gln1361Arg) missense change has a maximum subpopulation frequency of 0.060% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. This variant was reported in five individuals in a study of breast cancer, however it was not specified if the variant was found in cases or controls (PMID: 31871109). This variant is present in nine individuals in a database of women older than 70 years of age who have never had cancer (FLOSSIES database, https://whi.color.com/). To our knowledge, this variant has not been reported in individuals with ataxia telangiectasia. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. |

RCV003153441 | SCV003936024 | uncertain significance | Familial cancer of breast | 2023-06-06 | criteria provided, single submitter | clinical testing | A variant of uncertain significance was detected in the ATM gene. This sequence change replaces glutamine with arginine at codon 1361 of the ATM protein (p.Gln1361Arg). This variant is present in population databases (rs141921797, ExAC 0.07%). This variant has been observed in individual(s) with breast cancer (PMID: 23555315). ClinVar contains an entry for this variant (Variation ID: 185234). In-silico predictions show benign computational verdict based on 9 benign predictions from PolyPhen, BayesDel_addAF, DEOGEN2, EIGEN, LIST-S2, MVP, MutationTaster, PrimateAI and SIFT vs 4 pathogenic predictions from DANN, FATHMM-MKL, M-CAP and MutationAssessor and the position is not highly conserved. Therefore, it has been classified as a Variant of Uncertain Significance. Heterozygous pathogenic/likely pathogenic mutations in ATM gene cause breast cancer susceptibility (OMIM#114480). |
