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]

The p.R2461C variant (also known as c.7381C>T), located in coding exon 49 of the ATM gene, results from a C to T substitution at nucleotide position 7381. The arginine at codon 2461 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration was previously reported in two individuals who underwent multi-gene panel testing and was classified as a variant of unknown significance. One individual was diagnosed with endometrial cancer and the other with early-onset colorectal cancer (Ring KL et al. Mod. Pathol. 2016 Nov;29:1381-9; Pearlman R et al. JAMA Oncol. 2017 Apr;3:464-471). This alteration was also reported in the heterozygous state in a Caucasian male meeting Chompret criteria who was diagnosed with spindle cell sarcoma of the liver at age 42 years (Ballinger ML et al. Lancet Oncol. 2016 Sep;17:1261-71). In addition, this alteration was also observed in individuals diagnosed with prostate cancer (Beebe-Dimmer JL et al. Prostate, 2018 04;78:321-326; Matejcic M et al. JCO Precis Oncol, 2020 Jan;4:32-43). 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. -

Review Status: criteria provided, single submitter

This missense variant replaces arginine with cysteine at codon 2461 of the ATM protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. In a large international case-control study, this variant was reported in 6/60466 breast cancer cases and 3/53461 controls (OR=1.768, 95%CI 0.442 to 7.071, p-value=0.515; PMID: 33471991). This variant has also been reported in individuals affected with early-onset or bilateral breast cancer (Color internal data), early-onset prostate cancer (PMID: 29356034), colorectal cancer (PMID: 28135145, 27978560), sarcoma (PMID: 27498913), and endometrial carcinoma (PMID: 27443514). This variant has been identified in 26/282686 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.7381C>T (p.Arg2461Cys) variant has an allele frequency of 0.000093 (0.009%, 25/268,148 alleles) in the gnomAD v2.1.1 non-cancer dataset, with a maximal frequency of 0.00064 (0.06%, 15/23,620 alleles) in the Afican subpopulation (no population frequency criterion met; http://gnomad.broadinstitute.org). It is not predicted to lead to a splicing alteration as per SPiCE predictor. A cryptic acceptor site is activated according to SpliceSiteFinderlike and MaxEnt, but its score slightly exceeds the natural one only according to SpliceSiteFinderlike and no splicing site is created/activated according to NNSplice and GeneSplicer. However, missense variant alters the protein function / structure on the in-silico prediction reports of REVEL and PROVEAN (PP3). There is no other supporting data that meet criteria for consideration. Therefore, the clinical significance of this variant is uncertain. Adapted ACMG/AMP rules applied as defined by the Spanish ATM working group: PP3 (PMID: 33280026). -

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). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

The ATM c.7381C>T variant is predicted to result in the amino acid substitution p.Arg2461Cys. This variant has been reported in individuals with endometrial, colorectal, and prostate cancer (Ring et al. 2016. PubMed ID: 27443514, Table S2; Pearlman et al. 2017. PubMed ID: 27978560, eTable 2; Beebe-Dimmer et al. 2018. PubMed ID: 29356034). This variant is reported in 0.060% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-108201014-C-T) and is interpreted as uncertain significance by the vast majority of clinical laboratories in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/142541/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: ATM c.7381C>T (p.Arg2461Cys) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8.4e-05 in 251274 control chromosomes. This frequency is not significantly higher than expected for a pathogenic variant in ATM causing Ataxia-Telangiectasia (8.4e-05 vs 0.004), allowing no conclusion about variant significance. c.7381C>T has been reported as a VUS in the literature in individuals undergoing hereditary cancer panel testing for a variety of cancer indications (example, Ring_2016, Pearlman_2017, Feliubadalo_2017). These report(s) do not provide unequivocal conclusions about association of the variant with Ataxia-Telangiectasia/breast cancer. At-least one co-occurrence with another pathogenic variant has been observed at our laboratory (BRCA1 c.2744_2745delCT, p.Ser915*), providing supporting evidence for a benign role in relationship to breast cancer but not Ataxia-Telangiectasia. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Eight clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (VUS, n=7; likely benign, n=1). Some submitters cite overlapping evidence utilized in the context of this evaluation. Based on the evidence outlined above, the variant was classified as likely benign. -
