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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: The ATM c.3372C>G (p.Tyr1124X) variant results in a premature termination codon, predicted to cause a truncated or absent ATM protein due to nonsense mediated decay, which are commonly known mechanisms for disease. This variant was found in 1/245674 control chromosomes (gnomAD) at a frequency of 0.0000041, which does not exceed the estimated maximal expected allele frequency of a pathogenic ATM variant (0.0010005). Multiple publications have cited the variant in affected individuals diagnosed with breast cancer or Ataxia-Telangiectasia. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Tyr1124*) in the ATM gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). This variant is present in population databases (rs587779833, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with ataxia-telangiectasia and breast and lung cancer (PMID: 10330348, 10817650, 26681312). ClinVar contains an entry for this variant (Variation ID: 127371). For these reasons, this variant has been classified as Pathogenic.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The ATM c.3372C>G (p.Tyr1124*) variant causes the premature termination of ATM protein synthesis. This variant has been reported in the published literature in individuals with breast cancer (PMIDs: 33302456 (2020), 26681312 (2015)). Additionally, this variant has been identified in the homozygous and compound heterozygous state in individuals with ataxia-telangiectasia (PMIDs: 10817650 (2000), 30639167 (2019), 10330348 (1999)). The frequency of this variant in the general population, 0.000004 (1/250920 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Y1124* pathogenic mutation (also known as c.3372C>G), located in coding exon 22 of the ATM gene, results from a C to G substitution at nucleotide position 3372. This changes the amino acid from a tyrosine to a stop codon within coding exon 22. This alteration has been reported as both heterozygous and homozygous in individuals diagnosed with ataxia-telangiectasia (Teraoka SN et al. Am. J. Hum. Genet. 1999 Jun;64:1617-31; Li A and Swift M. Am. J. Med. Genet. 2000 May;92:170-7; Minto H et al. Clin Immunol, 2019 03;200:55-63). Additionally, this alteration was identified in individuals diagnosed with breast and prostate cancer (Susswein LR et al. Genet Med, 2016 08;18:823-32; Lovejoy LA et al. Genes (Basel), 2020 12;11:; Matejcic M et al. JCO Precis Oncol, 2020 Jan;4:32-43). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant changes 1 nucleotide in exon 23 of the ATM gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in the homozygous and heterozygous state in individuals affected with ataxia telangiectasia (PMID: 10330348, 10817650). This variant has also been reported in an individual affected with breast and lung cancer (PMID: 26681312). This variant has been identified in 1/250920 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 Pathogenic.
