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]

Review Status: criteria provided, single submitter

Variant summary: The ATM c.6067G>A (p.Gly2023Arg) variant involves the alteration of a conserved nucleotide and 4/4 in silico tools predict a damaging outcome for this variant (SNPsandGO not captured due to low reliability index). This variant was found in 397/277154 (1 homozygote) control chromosomes (gnomAD), predominantly observed in the European (Non-Finnish) subpopulation at a frequency of 0.002368 (300/126680). This frequency is about 2 times the estimated maximal expected allele frequency of a pathogenic ATM variant (0.0010005), suggesting this is likely a benign polymorphism found primarily in the populations of European (Non-Finnish) origin. Multiple publications have cited the variant in affected BrC pts, along with multiple somatic occurrences in MCL and CLL pts. Skowronska_2012 suggestions, biallelic ATM inactivation in CLL patients was associated with disease progression and reduced survival. However, the variant has been reported to co-occur with a BRCA1 variant, although the exact variant was not indicated (Thorstenson_2003). In addition, two internal LCA samples report the variant to co-occur with a pathogenic ATM variant, c.6095G>A (p.Arg20232Lys) and BRCA1 variant, c.1326T>A (p.Cys442X). In addition, multiple clinical diagnostic laboratories cite the variant as "likely benign/benign." Taken together, this variant is classified as benign. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.6067G>A (p.Gly2023Arg) variant has an allele frequency of 0.0014 (0.14%, 374/268,256 alleles) in the gnomAD v2.1.1 non-cancer dataset, with a maximal frequency of 0.0023 (0.232%, 274/118,126 alleles) in the European (non-Finnish) subpopulation (BS1; 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). 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: BS1 + PP3 (PMID: 33280026). -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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 p.Gly2023Arg variant was identified in 15 of 8674 proband chromosomes (frequency: 0.002) from individuals or families with CLL, lymphoid neoplasms, colorectal or breast cancer and was identified in 2 of 1602 chromosomes (frequency: 0.001) from healthy individuals (Broeks 2008, Gronbaek 2002, Mangone 2015, Paglia 2010, Podralska 2018, Skowronska 2012, Thorstenson 2003, Yurgelun 2015, Balmana 2016, Tung 2016). The variant was also identified in dbSNP (ID: rs11212587) as "With other allele", ClinVar (classified as benign by two clinical laboratories; as likely benign by Invitae, Ambry Genetics and three other submitters; as uncertain significance by one submitter), Cosmic (3x in Large intestine, or Haematopoietic and lymphoid tissue), MutDB, and in LOVD 3.0 (3x) databases. The variant was not identified in COGR. The variant was identified in control databases in 397 of 277154 chromosomes (1 homozygous) at a frequency of 0.001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 10 of 24034 chromosomes (freq: 0.0004), Other in 7 of 6460 chromosomes (freq: 0.001), Latino in 36 of 34418 chromosomes (freq: 0.001), European in 300 of 126680 chromosomes (freq: 0.002), Ashkenazi Jewish in 1 of 10152 chromosomes (freq: 0.0001), East Asian in 1 of 18852 chromosomes (freq: 0.00005), Finnish in 22 of 25778 chromosomes (freq: 0.0009), and South Asian in 20 of 30780 chromosomes (freq: 0.0007). The p.Gly2023 residue is conserved in mammals but not in more distantly related organisms, and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In silico analysis predicted the variant induces or contributes to increased exon skipping (Caminsky 2016). In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
