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:2

Uncertain significance, no assertion criteria provided	clinical testing	Natera, Inc.	Jan 21, 2020	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 28, 2024	This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 2508 of the ATM protein (p.Gly2508Arg). This variant is present in population databases (rs754395517, gnomAD 0.008%). This missense change has been observed in individual(s) with clinical features of Lynch syndrome and/or prostate cancer (PMID: 25980754, 33436325). ClinVar contains an entry for this variant (Variation ID: 187265). 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. -

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jul 26, 2022	The p.G2508R variant (also known as c.7522G>A), located in coding exon 50 of the ATM gene, results from a G to A substitution at nucleotide position 7522. The glycine at codon 2508 is replaced by arginine, an amino acid with dissimilar properties. This variant was reported in 1/5560 prostate cancer cases and in 0/3353 controls of European ancestry (Karlsson Q et al. Eur Urol Oncol, 2021 08;4:570-579). This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Jul 11, 2022	This missense variant replaces glycine with arginine at codon 2508 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with Lynch syndrome-associated cancer and/or polyps (PMID: 25980754), an individual affected with prostate cancer (PMID: 33436325), and an individual affected with colorectal cancer (PMID: 34271781). In a large international case-control study, this variant was reported in 11/60466 breast cancer cases and 4/53461 unaffected controls (PMID: 33471991). This variant has also been identified in 6/281930 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 ATM c.7522G>A variant is predicted to result in the amino acid substitution p.Gly2508Arg. This variant has been identified in an individual undergoing Lynch syndrome-testing (Yurgelun et al. 2015. PubMed ID: 25980754, Table S2), an individual with glioblastoma multiforme (Lu et al. 2015. PubMed ID: 26689913, Table S12), and an individual with prostate cancer (Karlsson et al. 2021. PubMed ID: 33436325, Table S4). This variant is reported in 0.010% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-108202177-G-A) and is interpreted as uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/187265/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
