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]

Uncertain significance, no assertion criteria provided	clinical testing	Natera, Inc.	Feb 17, 2020	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Oct 17, 2022	This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 2935 of the ATM protein (p.Met2935Ile). This variant is present in population databases (rs772621438, gnomAD 0.05%). This missense change has been observed in individual(s) with breast cancer (PMID: 28580595). ClinVar contains an entry for this variant (Variation ID: 407626). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The isoleucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 12, 2024	The p.M2935I variant (also known as c.8805G>A), located in coding exon 60 of the ATM gene, results from a G to A substitution at nucleotide position 8805. The methionine at codon 2935 is replaced by isoleucine, an amino acid with highly similar properties. This variant was identified in 1/292 individuals with breast cancer (Xie Y et al. Clin. Genet., 2018 Jan;93:41-51). This variant was also reported in 13/60,466 breast cancer cases and in 7/53,461 controls (Dorling et al. N Engl J Med 2021 02;384:428-439). This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Jan 17, 2020	This missense variant replaces methionine with isoleucine at codon 2935 of the ATM protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been reported in a healthy control individual (PMID: 19781682). This variant has been identified in 9/251414 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. -
