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]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 19, 2023	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 13 of the ATM protein (p.Arg13His). This variant is present in population databases (rs778201041, gnomAD 0.003%). This missense change has been observed in individual(s) with breast cancer (PMID: 31780696). ClinVar contains an entry for this variant (Variation ID: 188171). 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 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. -

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Jan 04, 2024	This missense variant replaces arginine with histidine at codon 13 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast cancer (PMID: 28779002, 31780696). This variant has also been reported in an individual affected with ataxia-telangiectasia who was compound heterozygous for a truncation variant in the non-sense mediated decay region and a variant impacting a canonical +2 splice site, suggesting this variant may not be disease-causing (DOI: 10.37897/RJN.2021.2.11). This variant has been identified in 4/251386 chromosomes 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 submitter	clinical testing	Ambry Genetics	Aug 08, 2023	The p.R13H variant (also known as c.38G>A), located in coding exon 1 of the ATM gene, results from a G to A substitution at nucleotide position 38. The arginine at codon 13 is replaced by histidine, an amino acid with highly similar properties. This variant has been identified in breast cancer cohorts (Dutil J et al. Sci Rep, 2019 11;9:17769; Decker B et al. J Med Genet, 2017 11;54:732-741). This amino acid position is 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. -

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in at least three individuals with breast cancer (PMID: 28779002); Reported as a variant of uncertain significance in an individual with ataxia-telangectasia who was also heterozygous for two other variants in the ATM gene plausibly explaining the phenotype (Villagaray-Pacheco N et al. (2021) Ro J Neurol. 20 (2)); This variant is associated with the following publications: (PMID: 22895193, 29445900, 31780696, 28779002, Villagaray-Pacheco2021[Case Report]) -
