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]

Submissions by phenotype

Ataxia-telangiectasia syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 10, 2023This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 513 of the ATM protein (p.Gln513Arg). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This missense change has been observed in individual(s) with a personal and/or family history of hereditary breast and/or ovarian cancer (PMID: 27067391). ClinVar contains an entry for this variant (Variation ID: 453375). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Uncertain significance, criteria provided, single submitterclinical testingGeneDxDec 15, 2021Not observed at significant frequency in large population cohorts (Lek 2016); In silico analysis supports that this missense variant does not alter protein structure/function; Identified in patients with suspected hereditary breast and ovarian cancer (Mucaki 2016); This variant is associated with the following publications: (PMID: 27067391) -
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 19, 2021The p.Q513R variant (also known as c.1538A>G), located in coding exon 9 of the ATM gene, results from an A to G substitution at nucleotide position 1538. The glutamine at codon 513 is replaced by arginine, an amino acid with highly similar properties. This alteration has been reported in patients referred for hereditary breast and ovarian cancer testing (Mucaki EJ et al. BMC Med Genomics, 2016 Apr;9:19; Matis TS et al. NPJ Breast Cancer, 2021 Aug;7:109). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
