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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: The ATM c.7108A>G (p.Asn2370Asp) variant causes a missense change involving a non-conserved nucleotide with 4/4 in silico tools (SNPs&GO not captured due to low reliability index) predict a benign outcome, although these predictions have yet to be functionally assessed. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 1/120934, which does not exceed the estimated maximal expected allele frequency for a pathogenic ATM variant of 1/252 for Ataxia-Telangiectasia. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories. Because of the absence of clinical information and the lack of functional studies, the variant was classified as a "Variant of Uncertain Significance (VUS)," until additional information becomes available.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is denoted ATM c.7108A>G at the cDNA level, p.Asn2370Asp (N2370D) at the protein level, and results in the change of an Asparagine to an Aspartic Acid (AAT>GAT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. ATM Asn2370Asp 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 Aspartic Acid differ in some properties, this is considered a semi-conservative amino acid substitution. ATM Asn2370Asp occurs at a position that is not conserved and is located within the FAT 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 Asn2370Asp is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 2370 of the ATM protein (p.Asn2370Asp). This variant is present in population databases (rs767494363, gnomAD 0.002%). 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: 246353). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ATM protein function with a negative predictive value of 95%. 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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.N2370D variant (also known as c.7108A>G), located in coding exon 48 of the ATM gene, results from an A to G substitution at nucleotide position 7108. The asparagine at codon 2370 is replaced by aspartic acid, an amino acid with highly similar properties. 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.
