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]

This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 2707 of the ATM protein (p.Ser2707Cys). This variant is present in population databases (rs748016261, gnomAD 0.02%). This missense change has been observed in individual(s) with breast cancer (PMID: 29905759, 30287823). ClinVar contains an entry for this variant (Variation ID: 220257). 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 expected to disrupt ATM protein function with a positive 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. -

The p.S2707C variant (also known as c.8120C>G), located in coding exon 54 of the ATM gene, results from a C to G substitution at nucleotide position 8120. The serine at codon 2707 is replaced by cysteine, an amino acid with dissimilar properties. This variant has been identified in multiple individuals with a personal and/or family history of breast and/or ovarian cancer (Momozowa Y et al. Nat Commun 2018 10;9(1):4083; Wang J et al. Cancer Med, 2019 05;8:2074-2084; Shao D et al. Cancer Sci, 2020 Feb;111:647-657; Liu Y et al. Front Genet, 2023 Nov;14:1271710). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

The ATM c.8120C>G variant is predicted to result in the amino acid substitution p.Ser2707Cys. This variant was reported in both female and male breast cancer patients (Supplementary Data 1 & 2 in Momozawa et al. 2018. PubMed ID: 30287823; Table S1 in Zhang et al. 2018. PubMed ID: 29905759; Table S2 in Wang et al. 2019. PubMed ID: 30982232) however, it was also reported in controls (Supplementary Data 1 in Momozawa et al. 2018. PubMed ID: 30287823; Supplemental Table 2 in Okawa et al. 2022. PubMed ID: 36243179). This variant is reported in 0.027% of alleles in individuals of East Asian descent in gnomAD and has been interpreted as uncertain in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/220257/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
