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	Jan 16, 2024	This sequence change replaces arginine, which is basic and polar, with lysine, which is basic and polar, at codon 568 of the ATM protein (p.Arg568Lys). This variant is present in population databases (rs200381392, gnomAD 0.02%). This missense change has been observed in individual(s) with breast and cervical cancer (PMID: 30093976). ClinVar contains an entry for this variant (Variation ID: 142348). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The lysine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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	Jun 06, 2022	This missense variant replaces arginine with lysine at codon 568 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 reported in 17/60466 breast cancer cases and 13/53461 controls (OR=1.156, 95%CI 0.562 to 2.381, p-value=0.719; PMID: 33471991). This variant has been identified in 9/251228 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 03, 2023	The p.R568K variant (also known as c.1703G>A), located in coding exon 10 of the ATM gene, results from a G to A substitution at nucleotide position 1703. The arginine at codon 568 is replaced by lysine, an amino acid with highly similar properties. This alteration has been reported as a variant of unknown significance in an individual with a personal history of breast and cervical cancer from a cohort of 1191 cancer index patients who underwent clinical evaluation and testing with multigene panels (Chan GHJ et al. Oncotarget, 2018 Jul;9:30649-30660). This alteration was also detected in 4/5589 German BRCA1/2-negative probands with breast cancer (Hauke J et al. Cancer Med, 2018 Apr;7:1349-1358). 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. -
