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]

Variant summary: ATM c.3025G>C (p.Glu1009Gln) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 7.2e-06 in 276254 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.3025G>C in individuals affected with Ataxia-Telangiectasia and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 419680). Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 1009 of the ATM protein (p.Glu1009Gln). This variant is present in population databases (no rsID available, gnomAD 0.0009%). 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ATM protein function. ClinVar contains an entry for this variant (Variation ID: 419680). This variant has not been reported in the literature in individuals affected with ATM-related conditions. -

This variant is denoted ATM c.3025G>C at the cDNA level, p.Glu1009Gln (E1009Q) at the protein level, and results in the change of a Glutamic Acid to a Glutamine (GAG>CAG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. ATM Glu1009Gln was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Glutamic Acid and Glutamine differ in some properties, this is considered a semi-conservative amino acid substitution. ATM Glu1009Gln occurs at a position that is conserved across species and is located within the beta-adaptin interaction domain (Tavtigian 2009). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available information, it is unclear whether ATM Glu1009Gln is pathogenic or benign. We consider it to be a variant of uncertain significance. -

The p.E1009Q variant (also known as c.3025G>C), located in coding exon 19 of the ATM gene, results from a G to C substitution at nucleotide position 3025. The glutamic acid at codon 1009 is replaced by glutamine, an amino acid with highly similar properties. This alteration was not observed in 7051 unselected female breast cancer patients, 11241 female controls of Japanese ancestry, or in 53 unselected male breast cancer patients; however, it was reported with a carrier frequency of 0.00008 in 12490 male controls of Japanese ancestry (Momozawa Y et al. Nat Commun, 2018 10;9:4083). 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. -
