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:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeFeb 01, 2024This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1506 of the ATM protein (p.Val1506Met). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 216218). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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, no assertion criteria providedclinical testingNatera, Inc.Aug 02, 2021- -
not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGeneDxNov 04, 2015This variant is denoted ATM c.4516G>A at the cDNA level, p.Val1506Met (V1506M) at the protein level, and results in the change of a Valine to a Methionine (GTG>ATG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. ATM Val1506Met was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Valine and Methionine share similar properties, this is considered a conservative amino acid substitution. ATM Val1506Met occurs at a position that is conserved across species and is not located in a known functional domain (Tavtigian 2009, Stracker 2013). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether ATM Val1506Met is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2023The p.V1506M variant (also known as c.4516G>A), located in coding exon 29 of the ATM gene, results from a G to A substitution at nucleotide position 4516. The valine at codon 1506 is replaced by methionine, an amino acid with highly similar properties. This variant was reported in 1/60,466 breast cancer cases and in 0/53,461 controls (Dorling et al. N Engl J Med. 2021 02;384:428-439). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
