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]

Ataxia-telangiectasia syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 23, 2024	This sequence change replaces asparagine, which is neutral and polar, with histidine, which is basic and polar, at codon 206 of the ATM protein (p.Asn206His). This variant is present in population databases (rs587781829, gnomAD 0.0009%). This missense change has been observed in individual(s) with glioblastoma multiforme (PMID: 26689913). ClinVar contains an entry for this variant (Variation ID: 141543). 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 tolerated. 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:2

Uncertain significance, criteria provided, single submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	Sep 02, 2024	The ATM c.616A>C (p.Asn206His) variant has been reported in the published literature in an individual with glioblastoma (PMID: 26689913 (2015)). This variant has also been identified in a reportedly healthy individual (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared)). The frequency of this variant in the general population, 0.000004 (1/251218 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Sep 15, 2016	This variant is denoted ATM c.616A>C at the cDNA level, p.Asn206His (N206H) at the protein level, and results in the change of an Asparagine to a Histidine (AAT>CAT). This variant was identified in both the tumor and normal surrounding tissue of an individual with glioblastoma as well as the tumor of an individual with lymphoma (Lu 2015, Parry 2015). ATM Asn206His 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 Asparagine and Histidine differ in some properties, this is considered a semi-conservative amino acid substitution. ATM Asn206His occurs at a position that is not conserved and is not located in a known functional domain (Tavtigian 2009, Stracker 2013). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available evidence, it is unclear whether ATM Asn206His is pathogenic or benign. We consider it to be a variant of uncertain significance. -

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Apr 04, 2019	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Nov 09, 2023	The p.N206H variant (also known as c.616A>C), located in coding exon 5 of the ATM gene, results from an A to C substitution at nucleotide position 616. The asparagine at codon 206 is replaced by histidine, an amino acid with similar properties. This alteration has been reported in a patient with glioblastoma multiforme from a cohort of 4034 cancer cases from The Cancer Genome Atlas (Lu C et al. Nat Commun, 2015 Dec;6:10086). 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. -
