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]

Ataxia-telangiectasia syndrome

Uncertain:4

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 30, 2024	This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2866 of the ATM protein (p.Leu2866Val). This variant is present in population databases (rs368666328, gnomAD 0.007%). This missense change has been observed in individual(s) with endometrial cancer and/or prostate cancer (PMID: 27443514, 33436325). ClinVar contains an entry for this variant (Variation ID: 186482). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Counsyl	Mar 09, 2017	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 29, 2024	The p.L2866V variant (also known as c.8596C>G), located in coding exon 58 of the ATM gene, results from a C to G substitution at nucleotide position 8596. The leucine at codon 2866 is replaced by valine, an amino acid with highly similar properties. This alteration has been reported in endometrial, breast and prostate cancer cohorts, as well as in controls (Ring KL et al. Mod Pathol, 2016 11;29:1381-1389; Decker B et al. J Med Genet, 2017 11;54:732-741; Tiao G et al. Leukemia, 2017 10;31:2244-2247; Karlsson Q et al. Eur Urol Oncol, 2021 Aug;4:570-579). 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
