Hereditary cancer-predisposing syndrome Uncertain:3Benign:2
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 16, 2018 | 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:3
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jan 08, 2019 | This variant is denoted ATM c.7740A>C at the cDNA level, p.Arg2580Ser (R2580S) at the protein level, and results in the change of an Arginine to a Serine (AGA>AGC). This variant has been observed in individuals with breast or ovarian cancer (Lu 2015, Tung 2016). ATM Arg2580Ser was observed at an allele frequency of 0.03% (11/34,414) in individuals of Latino ancestry in large population cohorts (Lek 2016). This variant is not located in a known functional domain. In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether ATM Arg2580Ser is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Athena Diagnostics | Jul 07, 2023 | Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is uninformative in assessment of its pathogenicity (http://gnomad.broadinstitute.org). Computational tools predict that this variant is not damaging. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Quest Diagnostics Nichols Institute San Juan Capistrano | Jul 07, 2023 | In the published literature, this variant has been reported in individuals with breast cancer (PMIDs: 35264596 (2022), 32936981 (2021), 32658311 (2021), 32039725 (2020), 31159747 (2019), 31780696 (2019), 26976419 (2016)), ovarian cancer (PMID: 26689913 (2015)), or prostate cancer (PMID: 31214711 (2020)). In addition, this variant has been reported in control individuals (PMID: 32658311 (2021), 28652578 (2017)). The frequency of this variant in the general population, 0.00023 (8/35436 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. - |

not specified Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Apr 25, 2024 | Variant summary: ATM c.7740A>C (p.Arg2580Ser) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0003 in 152224 control chromosomes, predominantly at a frequency of 0.002 within the Latino subpopulation in the gnomAD database (v3). The observed variant frequency within Latino control individuals in the gnomAD database is approximately 2 fold of the estimated maximal expected allele frequency for a pathogenic variant in ATM causing Breast Cancer phenotype (0.001), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Latino origin. c.7740A>C has been reported in the literature in individuals affected with breast cancer, ovarian cancer and Chronic Lymphocytic Leukemia patients (Tung_2016, Lu_2015, Tiao_2017, Dutil_2019, Tsaousis_2019, Da Costa_2020). These report(s) 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. The following publications have been ascertained in the context of this evaluation (PMID: 26689913, 26787654, 26976419, 28652578, 31159747, 32039725, 31780696). ClinVar contains an entry for this variant (Variation ID: 127448). Based on the evidence outlined above, the variant was classified as likely benign. - |
