Genes affected
ATM (HGNC:795): (ATM serine/threonine kinase) The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder. [provided by RefSeq, Aug 2010]

The ATM c.2159G>A (p.Arg720His) variant has been reported in the published literature in individuals with a personal or family history of breast and/or ovarian cancer (PMIDs: 35218119 (2022), 32068069 (2020), 30287823 (2018), 28779002 (2017), 20305132 (2010), 33471991 (2021), see LOVD (http://databases.lovd.nl/shared)), biliary tract cancer (PMID: 36243179 (2022)), prostate cancer (PMID: 31214711 (2020)), urothelial carcinoma (PMID: 33588785 (2021)), and melanoma (PMID: 34262154 (2021)). This variant has also been observed in reportedly healthy individuals (PMIDs: 30287823 (2018), 31214711 (2020), 33471991 (2021), 36243179 (2022), 35218119 (2022)). The frequency of this variant in the general population, 0.00025 (5/19854 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. -

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 720 of the ATM protein (p.Arg720His). This variant is present in population databases (rs55830714, gnomAD 0.03%). This missense change has been observed in individual(s) with breast cancer, melanoma, ovarian cancer, and/or urothelial cancer (PMID: 20305132, 28779002, 30287823, 32068069, 33588785, 34262154). ClinVar contains an entry for this variant (Variation ID: 181924). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ATM protein function with a negative predictive value of 95%. 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. -

Variant summary: ATM c.2159G>A (p.Arg720His) 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 0.0002 in 298502 control chromosomes (gnomAD). This frequency is not higher than expected for a pathogenic variant in ATM causing Breast Cancer (0.0002 vs 0.001), allowing no conclusion about variant significance. c.2159G>A has been reported in the literature in individuals affected with Breast Cancer/or Ovarian cancer (examples: Bernstein_2010, Momozawa_2018, Kwong_2020, Dalmasso_2021 and Dorling_2021) but also in unaffected controls (examples: Momozawa_2018,and Dorling_2021). These reports 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. Eight clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and all classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This missense variant replaces arginine with histidine at codon 720 of the ATM protein. Computational prediction tools and conservation analyses suggest that this variant may not impact protein structure and function. To our knowledge, functional studies have not been performed for this variant. This variant has been reported in individuals affected with breast cancer (PMID: 20305132) including three case-control studies (PMID: 28743247, 30287823, 33471991). In the first case-control study, conducted in the UK, this variant was reported in 1/13087 breast cancer cases and 0/5488 controls (PMID: 28743247). In a second case-control study with Japanese participants, this variant was reported in 10/7051 female breast cancer cases, 28/11241 female controls (OR=0.569, 95%CI 0.2 to 1.2), 0/53 male breast cancer cases, and 19/12490 male controls (PMID: 30287823). A third case-control study included participants from multiple countries and reported this variant in 9/60457 breast cancer cases and 8/53453 controls (OR=0.995, 95%CI 0.384 to 2.578, p-value=1; PMID: 33471991). This variant has been identified in 15/282402 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. -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

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. -

The ATM c.2159G>A variant is predicted to result in the amino acid substitution p.Arg720His. This variant has been reported in individuals with breast and/or ovarian cancer (Table S2, Berstein et al. 2010. PubMed: 20305132; Table S5, Decker et al. 2017. PubMed ID: 28779002; Table S1, Kwong et al. 2020. PubMed ID: 32068069). It has been reported in a urothelial carcinoma specimen (Additional Data 3, Yang et al. 2021. PubMed ID: 33588785) and a melanoma cohort study (Supplement, Dalmasso et al. 2021. PubMed ID: 34262154). It has also been reported in cases and controls from a breast cancer cohort study and a prostate cancer cohort study (Supplement, Momozawa et al. 2018. PubMed ID: 30287823; Supplement, Momozawa et al. 2020. PubMed ID: 31214711). This variant is reported in 0.025% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-108126976-G-A) and is interpreted as uncertain significance in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/181924/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
