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	GeneDx	Nov 05, 2019	Not observed at a significant frequency in large population cohorts (Lek 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Observed in individuals with breast cancer (Momozawa 2018); This variant is associated with the following publications: (PMID: 30287823) -
Uncertain significance, criteria provided, single submitter	clinical testing	Athena Diagnostics	Mar 03, 2020	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	Mar 03, 2020	The best available variant frequency is uninformative because there are too few occurrences in population data. 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 damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Sep 26, 2022	The p.R451H variant (also known as c.1352G>A), located in coding exon 9 of the ATM gene, results from a G to A substitution at nucleotide position 1352. The arginine at codon 451 is replaced by histidine, an amino acid with highly similar properties. This alteration was observed in 3/7051 unselected female breast cancer patients and was observed with an allele frequency of 0.00018 in 11241 female controls of Japanese ancestry. In addition, it was not observed in unselected male breast cancer patients and was observed in 5/12490 male controls of Japanese ancestry (Momozawa Y et al. Nat Commun, 2018 10;9:4083). This alteration has been reported with a carrier frequency of 0.00052 in 7636 unselected prostate cancer patients and 0.65 in 12366 male controls of Japanese ancestry (Momozawa Y et al. J Natl Cancer Inst, 2020 04;112:369-376). 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Oct 27, 2023	This missense variant replaces arginine with histidine at codon 451 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. In a large international case-control study, this variant was absent in 60466 breast cancer cases and reported in 1/53461 controls (PMID: 33471991). In a separate case-control study conducted in Japan, this variant was reported in 3/7051 women affected with breast cancer, 2/11241 unaffected women, 0/53 men affected with breast cancer, and 8/12490 unaffected men (PMID: 30287823). In a third study the variant was reported in 4/7636 prostate cancer cases & 8/12366 unaffected controls (PMID: 31214711). This variant has been identified in 2/251368 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. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 451 of the ATM protein (p.Arg451His). This variant is present in population databases (rs554805703, gnomAD 0.01%). This missense change has been observed in individual(s) with breast cancer (PMID: 30287823). ClinVar contains an entry for this variant (Variation ID: 407670). 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 disruptive. 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. -
