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]

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 2708 of the ATM protein (p.Asp2708Asn). This variant is present in population databases (rs587782719, gnomAD 0.003%). This missense change has been observed in individuals with ataxia telangiectasia (A-T) and/or cancer (PMID: 16941484, 21665257, 21792198, 22071889, 23454770, 23632773, 27913932, 29909963). ClinVar contains an entry for this variant (Variation ID: 142791). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ATM protein function. Experimental studies have shown that this missense change affects ATM function (PMID: 19431188, 22071889, 23454770, 23632773). For these reasons, this variant has been classified as Pathogenic. -

This missense variant replaces aspartic acid with asparagine at codon 2708 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). Functional studies have shown that this variant results in reduced ATM kinase activity (PMID: 19431188). This variant has been reported in the compound heterozygous state with an additional pathogenic ATM variant in individuals affected with ataxia telangiectasia (PMID: 16941484, 17124347, 17910737, 19431188, 21665257, 21792198, 22071889, 23632773, 25122203, 30338439). It has been reported that cells derived from some of these individuals display reduced kinase activity, protein expression and irradiation response and increased radiosensitivity (PMID: 22071889, 23632773). This variant has also been reported in individuals affected with breast cancer (PMID: 27913932, 28779002). This variant has been identified in 1/251356 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Based on the available evidence, this variant is classified as Likely Pathogenic. -

The c.8122G>A (p.Asp2708Asn) variant appears only once in the gnomAD v2.1.1 non-cancer dataset, specifically in the South-Asian subpopulation (PM2; http://gnomad.broadinstitute.org). This missense variant is not predicted to lead to a splicing alteration as per SPiCE predictor and no splicing site is created/activated according to at least 3 splicing predictors of the set SpliceSiteFinderlike - MaxEntScan - NNSplice – GeneSplicer, but it alters the protein function / structure on the in-silico prediction reports of REVEL and PROVEAN (PP3). It has been described in trans with the pathogenic ATM variant c.2250G>A in two ataxia-telangiectasia probands and together (unknown phase) with the pathogenic ATM variant c.3712_3716del in another ataxia-telangiectasia proband, which awards 2.5 points to this variant as per ClinGen SVI Recommendation for in trans Criterion (PM3_Strong; PMID: 22071889, 16941484, 17124347). Studies in ataxia-telangiectasia patient carrier cells show no autophosphorilation in Serine 1981 and no (or trace) phosphorylation of 4 substrates upon irradiation, confirmed with two substrates by functional studies with the variant protein modelled in an ATM-null lymphoblastoid cell line. Intermediate irradiation sensitivity was found in a micronuclei assay (PS3_Moderate; PMID: 22071889, 23632773, 19431188). Therefore, this variant meets criteria to be classified as likely pathogenic. Adapted ACMG/AMP rules were applied as defined by the Spanish-ATM Variant Curation Panel: PM2 + PP3 + PM3_Strong + PS3_Moderate. Adapted ACMG/AMP rules applied as defined by the Spanish ATM working group: PVS1 + PM2 (PMID: 33280026). -

The p.D2708N pathogenic mutation(also known as c.8122G>A), located in coding exon 54 of the ATM gene, results from a G to A substitution at nucleotide position 8122. The aspartic acid at codon 2708 is replaced by asparagine, an amino acid with highly similar properties. This alteration has been reported in conjunction with other pathogenic ATM mutations (phase confirmed in two cases) in several individuals with classic and variant ataxia telangiectasia (AT) (Micol R et al. J. Allergy Clin. Immunol. 2011;128(2):382-9; Claes K et al. Neuromolecular Med. 2013;15(3):447-57; Cavalieri S et al. Ann. Hum. Genet. 2008;72(Pt 1):10-8; Magliozzi M et al. Dis. Markers 2006; 22(4):257-64). In two studies, this alteration was shown to demonstrate a significant reduction in ATM protein expression and kinase activity, as well as mislocalization of the protein (Jacquemin V et al. Eur. J. Hum. Genet. 2012;20(3):305-12; Barone G et al. Hum. Mutat. 2009;30(8):1222-30). In addition, a disease-causing mutation, p.D2708E, has been described at the same codon (Heinrich T et al. Eur. J. Pediatr. 2006; 165:250-7; Bisgin A et al. Biomed Res Int 2018 May;2018:9647253, Micol R et al. J. Allergy Clin. Immunol. 2011 Aug;128(2):382-9.e1; Jacquemin V et al. Eur. J. Hum. Genet. 2012; 20:305-12.). This amino acid position is highly conserved in available vertebrate species. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In addition, the in silico prediction for this alteration is inconclusive. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -

The ATM c.8122G>A; p.Asp2708Asn variant (rs587782719), is reported in the literature in a compound heterozygous state in multiple individuals affected with ataxia-telangiectasia (A-T; Cavalieri 2006, Claes 2013, Jacquemin 2012, Magliozzi 2006, Prodosmo 2013, Reiman 2011) and one heterozygous individual with bilateral breast cancer and ovarian cancer (Tavera-Tapia 2017). This variant is reported as likely pathogenic by multiple laboratories in ClinVar (Variation ID: 142791), and is also largely absent from general population databases (not found in 1000 Genomes Project or Exome Variant Server, and one heterozygous individual in Genome Aggregation Database), indicating it is not a common polymorphism. The asparagine at codon 2708 is highly conserved, and functional analyses of the variant protein show reduced kinase activity and increased radiosensitivity (Barone 2009, Claes 2013, Jacquemin 2012). Based on available information, this variant is considered to be likely pathogenic. Pathogenic variants in the ATM gene follow an autosomal recessive inheritance pattern and are associated with ataxia-telangiectasia (A-T; MIM: 208900), and an autosomal dominant inheritance pattern and are associated with an increased risk for breast cancer (MIM: 114480).

Variant summary: ATM c.8122G>A (p.Asp2708Asn) results in a conservative amino acid change located in the catalytic domain (IPR044107) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 (i.e., 1 heterozygote) in 251356 control chromosomes (gnomAD v2, exomes cohort). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.8122G>A has been reported in the literature in multiple compound heterozygous individuals affected with classic- and variant Ataxia-Telangiectasia (A-T) (e.g., Thompson_2005, Cavalieri_2006, Reiman_2011, Jacquemin_2012, Prodosmo_2013, Claes_2013), and in heterozygous individuals affected with various tumor phenotypes, including prostate-, breast/ovarian-, and pancreatic cancer (e.g., Hata_2021, Karlsson_2021, Tavera-Tapia_2017, Dorling_2021). These data indicate that the variant is very likely to be associated with disease. Publications also reported experimental evidence evaluating an impact on protein function, and demonstrated decreased protein levels and kinase activity in an in vitro expression system (Barone_2009), and in patient derived cells (e.g. Reiman_2011, Jacquemin_2012, Prodosmo_2013, Claes_2013). The following publications have been ascertained in the context of this evaluation (PMID: 19431188, 16941484, 23632773, 34755017, 22071889, 33436325, 23454770, 21792198, 27913932, 15928302, 29909963, 33471991). Multiple ClinVar submitters (evaluation after 2014) have cited the variant and all laboratories classified the variant as pathogenic (n = 4) or likely pathogenic (n = 8). Based on the evidence outlined above, the variant was classified as pathogenic. -
