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, criteria provided, single submitter	clinical testing	Mendelics	Jul 02, 2018	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 22, 2023	This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 982 of the ATM protein (p.Arg982Cys). This variant is present in population databases (rs587779830, gnomAD 0.007%). This missense change has been observed in individual(s) with prostate cancer or breast cancer (PMID: 33436325, 35264596). ClinVar contains an entry for this variant (Variation ID: 127363). 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 disruptive. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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:3

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 03, 2024	The p.R982C variant (also known as c.2944C>T), located in coding exon 19 of the ATM gene, results from a C to T substitution at nucleotide position 2944. The arginine at codon 982 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration was detected in 1/1135 Chinese patients with gastric cancer (Zhang C et al. J Med Genet, 2023 Aug;60:760-768), in a cohort of 151 patients diagnosed with epithelial breast cancer in the southernmost region of Thailand (Sukpan P et al. J Pers Med, 2023 Nov;13), and was detected in a cohort of 1663 Brazilian breast cancer patients who underwent hereditary multigene panel testing (Guindalini RSC et al. Sci Rep, 2022 Mar;12:4190). This variant has been reported in 2/5560 prostate cancer cases and in 0/3353 controls of European ancestry (Karlsson Q et al. Eur Urol Oncol, 2021 Aug;4:570-579), and has also been reported in the germline of 1/8920 ethnically matched normal population control subjects but was not seen in 516 samples from a study of chronic lymphocytic leukemia patients of European descent (Tiao G et al. Leukemia, 2017 Oct;31:2244-2247). This alteration has also been reported in at least one subject in a study of 13087 breast cancer cases and 5488 control individuals in the UK (Decker B et al. J Med Genet, 2017 11;54:732-741). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. 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	Feb 16, 2023	This missense variant replaces arginine with cysteine at codon 982 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). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with prostate cancer (PMID: 33436325). This variant has been identified in 5/251040 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. -
