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 creates a premature translational stop signal (p.Ser2812Phefs*2) 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 (rs767533596, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with breast cancer (PMID: 26824983). This variant is also known as c.8434_8435delTC. ClinVar contains an entry for this variant (Variation ID: 407667). For these reasons, this variant has been classified as Pathogenic. -

The c.8435_8436delCT pathogenic mutation, located in coding exon 57 of the ATM gene, results from a deletion of two nucleotides at nucleotide positions 8435 to 8436, causing a translational frameshift with a predicted alternate stop codon (p.S2812Ffs*2). This alteration was identified amongst cohorts of 1836 Chinese prostate cancer patients, 282 Chinese gastric cancer patients, and 1338 Chinese high-risk breast cancer patients (Zhu Y et al. J Natl Compr Canc Netw, 2021 Oct;20:54-62; Ji K et al. Chin J Cancer Res, 2020 Aug;32:508-515; Kwong A et al. J Mol Diagn, 2020 Apr;22:544-554). 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. -
