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]

Collection Method: clinical testing

The ATM c.2251-10T>G variant (rs730881346), also known as IVS16-10T>G, is reported in the literature in multiple individuals with ataxia-telangiectasia, both in the homozygous state and in trans to other pathogenic variants (Becker-Catania 2000, Buzin 2003, Stankovic 1998, Telatar 1998). This variant has also been reported in an individual affected with breast cancer (Susswein 2016). The c.2251-10T>G variant is reported as pathogenic/likely pathogenic by multiple laboratories in ClinVar (Variation ID: 181926), and it is found on only three chromosomes in the Genome Aggregation Database, indicating it is not a common polymorphism. This is an intronic variant in a moderately conserved nucleotide, and computational analyses (Alamut v.2.11) predict that this variant impacts splicing by creating a novel cryptic acceptor splice site, leading to inclusion of nine nucleotides containing a premature stop codon. RNA studies from patient cells containing this variant support this effect on splicing (Teraoka 1999), and immunoblotting performed on cells homozygous for this variant indicate no detectable ATM variant present (Stankovic 1998, Wang 2017). Based on available information, this variant is considered to be pathogenic. References: Becker-Catania SG et al.

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change falls in intron 14 of the ATM gene. It does not directly change the encoded amino acid sequence of the ATM protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or altered protein product. This variant is present in population databases (rs730881346, gnomAD 0.002%). This variant has been observed in individuals with ataxia-telangiectasia and/or breast cancer (PMID: 9443866, 9463314, 10330348, 10873394, 12552559, 26681312). It has also been observed to segregate with disease in related individuals. This variant is also known as IVS16-10T>G or 2249ins9nt. ClinVar contains an entry for this variant (Variation ID: 181926). Studies have shown that this variant alters ATM gene expression (PMID: 9463314, 10873394, 21792198). Studies have shown that this variant results in activation of a cryptic splice site, and produces a non-functional protein and/or introduces a premature termination codon (internal data). For these reasons, this variant has been classified as Pathogenic. -

Variant summary: ATM c.2251-10T>G alters a conserved nucleotide located at a position not widely known to affect splicing. Several computational tools predict a significant impact on normal splicing: Four predict the variant creates a 3' acceptor site. Two predict the variant abolishes a 3' acceptor site. Experimental evidence in support of these predictions demonstrated the variant to create a novel splice site and cause the insertion of 9 nucleotides eventually leading to truncation of the protein (Teraoka_1999). The variant allele was found at a frequency of 1.1e-05 in 275962 control chromosomes (gnomAD). c.2251-10T>G has been reported in the literature in multiple individuals affected with Ataxia-Telangiectasia (Reiman_2011, Buzin_2003, Becker-Catania_2000, Telatar_1998). The variant has also been reported in individuals affected with breast and pancreatic cancer (Hu_2018, Susswein_2016). These data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 12552559, 10330348, 10873394, 26681312, 21792198, 9443866, 28281021, 29922827, 28182994). Ten submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 and classified as pathogenic/likely pathogenic (n=9) and VUS (n=1). Based on the evidence outlined above, the variant was classified as pathogenic. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant causes a T to G nucleotide substitution at the -10 position of intron 14 of the ATM gene. Splice site prediction tools predict that this variant may create an alternative splice acceptor site. The use of this splice site is predicted to create a premature translation termination signal and is expected to result in an absent or non-functional protein product. Cell lines that are homozygous for this variant are reported to have undetectable ATM protein and autophosphorylation activity (PMID: 28182994). This variant (also known as IVS16-10T>G in the literature) has been reported in the homozygous state and compound heterozygous state in individuals affected with ataxia-telangiectasia (PMID: 9443866, 9463314, 10330348, 10873394, 12552559, 21792198, 34539671). Cells derived from some of these individuals have shown reduced or absent ATM protein levels and undetectable ATM kinase activity (PMID: 10873394, 21792198). This variant has also been reported in individuals affected with breast cancer and pancreatic cancer (PMID: 26681312, 28281021, 28779002, 29922827). This variant has been identified in 3/281524 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of ATM function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Likely Pathogenic. -

The c.2251-10T>G intronic pathogenic mutation results from a T to G substitution 10 nucleotides upstream from coding exon 14 in the ATM gene. This alteration has been reported in conjunction with a second, pathogenic mutation in multiple individuals diagnosed with ataxia-telangiectasia (Telatar M et al. Am. J. Hum. Genet. 1998 Jan;62:86-97; Teraoka SN et al. Am. J. Hum. Genet. 1999 June;64:1617-31; Becker-Catania SG et al. Mol. Genet. Metab. 2000 Jun;70:122-33; Campbell C et al. Hum. Mutat. 2003 Jan;21:80-85; Buzin CH et al. Hum. Mutat. 2003 Feb;21:123-31). In addition, this alteration has been identified in individuals diagnosed with breast cancer (Susswein LR et al. Genet. Med. 2016 Aug;18:823-32; Decker B et al. J. Med. Genet. 2017 Nov;54:732-741). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In silico splice site analysis predicts that this alteration will weaken the native splice acceptor site and will result in the creation or strengthening of a novel splice acceptor site. RNA studies showed abnormal splicing in the set of samples tested (Ambry internal data). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -

The ATM c.2251-10T>G variant disrupts a canonical splice-acceptor site and interferes with normal ATM mRNA splicing. This variant has been reported in the published literature in individuals with breast cancer (PMIDs: 26681312 (2015), 28779002 (2017)), breast cancer and/or ovarian cancer (PMIDs: 28281021 (2017), 35626031 (2022)), pancreatic cancer (PMIDs: 29922827 (2018), 37345735 (2023)), leukemia (PMIDs: 16014569 (2005), 37450374 (2023)) and lymphopenia (PMID: 34539671 (2021)), as well as in the biallelic state with a second pathogenic variant in individuals with ataxia telangiectasia (PMIDs: 9443866 (1998), 9463314 (1998), 10873394 (2000), 12552559 (2003)). The frequency of this variant in the general population, 0.000023 (3/129008 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using software algorithms for the prediction of the effect of nucleotide changes on splicing yielded predictions that this variant may affect proper ATM mRNA splicing. Based on the available information, this variant is classified as pathogenic. -

The ATM c.2251-10T>G variant is predicted to interfere with splicing. In the literature this variant has been referred to as IVS16-10T>G and 2249ins9nt. This variant has been reported in the homozygous state in an individual with ataxia telangiectasia (Stankovic et al. 1998. PubMed ID: 9463314) and along with a second pathogenic variant in multiple individuals with ataxia telangiectasia (Telatar et al. 1998. PubMed ID: 9443866; Becker-Catania et al. 2000. PubMed ID: 10873394; Stankovic et al. 1998. PubMed ID: 9463314; Buzin et al. 2003. PubMed ID: 12552559). Additionally, this variant has been reported in the heterozygous state in an individual with breast cancer (Table S1, Susswein et al. 2016. PubMed ID: 26681312) and another individual with pancreatic cancer (eTable 3, Hu et al. 2018. PubMed ID: 29922827). cDNA analysis indicates this variant leads to the creation of a novel splice acceptor site and results in premature protein termination (Stankovic et al. 1998. PubMed ID: 9463314; Teraoka et al. 1999. PubMed ID: 10330348). This variant is present in 3 out of 281,524 alleles in the gnomAD database and has been interpreted as pathogenic/likely pathogenic in the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/181926/). Based on the available evidence, we interpret the ATM c.2251-10T>G variant as pathogenic. -
