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]

Likely pathogenic, criteria provided, single submitter	clinical testing	Counsyl	Dec 15, 2015	- -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Dec 22, 2023	This sequence change creates a premature translational stop signal (p.Tyr2334Glnfs*4) 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 (rs763554569, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with prostate cancer (PMID: 27433846). ClinVar contains an entry for this variant (Variation ID: 187035). For these reasons, this variant has been classified as Pathogenic. -

Hereditary cancer-predisposing syndrome

Pathogenic:3

Pathogenic, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Jan 15, 2020	This variant deletes 4 nucleotides in exon 48 of the ATM gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been identified in 1/251036 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. -

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Sep 05, 2023	The c.7000_7003delTACA pathogenic mutation, located in coding exon 47 of the ATM gene, results from a deletion of 4 nucleotides at positions 7000 to 7003, causing a translational frameshift with a predicted alternate stop codon (p.Y2334Qfs*4). This alteration was identified in 1/692 men with metastatic prostate cancer who were unselected for family history of cancer or age at diagnosis (Pritchard CC et al. N. Engl. J. Med. 2016 Aug;375(5):443-53). This alteration was also reported in a woman with breast cancer, melanoma, and a family history of breast cancer (Torrezan GT et al. Front Genet, 2018 May;9:161). 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. -
