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]

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

This sequence change replaces phenylalanine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 897 of the ATM protein (p.Phe897Ile). This variant is present in population databases (rs147122522, gnomAD 0.006%). This missense change has been observed in individual(s) with breast cancer, gynecological cancer, melanoma, and/or pancreatic cancer (PMID: 28726808, 29371908, 34262154). ClinVar contains an entry for this variant (Variation ID: 188232). 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. -

The ATM c.7919C>T (p.Thr2640Ile) missense change has a maximum subpopulation frequency of 0.0062% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect of this variant on protein function, and to our knowledge functional studies have not been performed. This variant has been identified in individuals with breast and pancreatic cancer (PMID: 28726808, 28779002). Additionally, it has been reported to co-occur with another ATM variant, p.Trp156Ter, in an individual diagnosed with ovarian cancer; however, the phase of these variants was not determined (PMID: 29371908). 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. -

This missense variant replaces phenylalanine with isoleucine at codon 897 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. In an international breast cancer case-control meta-analysis, this variant was detected in 3/60466 cases and 2/53461 unaffected controls (PMID: 33471991). This variant has also been observed with a second ATM variant in an individual affected with ovarian cancer (PMID: 29371908). This variant has been identified in 8/251362 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. -

The p.F897I variant (also known as c.2689T>A), located in coding exon 17 of the ATM gene, results from a T to A substitution at nucleotide position 2689. The phenylalanine at codon 897 is replaced by isoleucine, an amino acid with highly similar properties. This alteration has been reported in individuals diagnosed with breast, ovarian, and pancreatic cancer (Chaffee K et al. Genet. Med. 2018 01;20(1):119-127; Decker B et al. J. Med. Genet. 2017 11;54(11):732-741; Dominguez-Valentin M et al. Hered Cancer Clin Pract 2018 Jan;16:4). In one of these individuals, this alteration was found to co-occur with an ATM truncating mutation, p.W156*; however, phase was not determined (Dominguez-Valentin M et al.). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Variant summary: ATM c.2689T>A (p.Phe897Ile) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 3.2e-05 in 251362 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.2689T>A has been reported in the literature in individuals affected with pancreatic, breast, and ovarian cancers, as well as melanoma (e.g. Decker_2017, Chaffee_2018 Dominguez-Valentin_2018, Dalmasso_2021), including one case where it was reported as co-occurring with a pathogenic variant (ATM c.468G>A, p.Trp156X; Dominguez-Valentin_2018), providing supporting evidence for a benign role. 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 all classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
