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]

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthMar 20, 2023This missense variant replaces aspartic acid with valine at codon 985 of the ATM protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with ATM-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 28, 2022The p.D985V variant (also known as c.2954A>T), located in coding exon 19 of the ATM gene, results from an A to T substitution at nucleotide position 2954. The aspartic acid at codon 985 is replaced by valine, an amino acid with highly dissimilar properties. This alteration has been reported in at least one subject in a study of 13087 breast cancer cases and 5488 control individuals in the UK (Decker B et al. J. Med. Genet., 2017 11;54:732-741). This amino acid position is not well 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. -
Ataxia-telangiectasia syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 04, 2023This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 985 of the ATM protein (p.Asp985Val). This variant is not present in population databases (gnomAD no frequency). 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: 219567). 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. -
not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGeneDxSep 14, 2017This variant is denoted ATM c.2954A>T at the cDNA level, p.Asp985Val (D985V) at the protein level, and results in the change of an Aspartic Acid to a Valine (GAT>GTT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. ATM Asp985Val was not observed in large population cohorts (NHLBI Exome Sequencing Project, The 1000 Genomes Consortium 2015, Lek 2016). Since Aspartic Acid and Valine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. ATM Asp985Val occurs at a position where amino acids with properties similar to Aspartic Acid are tolerated across species and is located within the beta-adaptin interaction domain (Tavtigian 2009). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available evidence, it is unclear whether ATM Asp985Val is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -
