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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 1568 of the ATM protein (p.His1568Arg). This variant is present in population databases (rs368830730, gnomAD 0.009%). This missense change has been observed in individual(s) with clinical features of ATM-related conditions (PMID: 30995915, 31159747). ClinVar contains an entry for this variant (Variation ID: 142472). 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 arginine 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. -

The ATM c.4703A>G (p.His1568Arg) variant has been reported in the published literature in individuals with personal and/or family history of breast and/or ovarian cancer (PMIDs: 31159747 (2019), 32957588 (2020), 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared)) and chronic lymphocytic leukemia (PMID: 28652578 (2017)). It has also been found in reportedly healthy individuals (PMIDs: 30287823 (2018), 31159747 (2019), 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared)). The frequency of this variant in the general population, 0.000088 (10/113434 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. 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 benign. Based on the available information, we are unable to determine the clinical significance of this variant. -

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with personal and/or family histories of cancer and in unaffected controls (Momozawa 2018, Tsaousis 2019, Germani 2020); This variant is associated with the following publications: (PMID: 27720647, 30995915, 31159747, 32957588, 30287823) -

The ATM p.His1568Arg variant was identified in 1 of 40,106 proband chromosomes (frequency: 0.00003) from individuals with unspecified hereditary cancer and was present in 1 of 24,980 control chromosomes (frequency: 0.00004) from healthy individuals (Momozawa 2018, Mu 2016). The variant was identified in dbSNP (rs368830730) as â€šÃ„Ãºwith uncertain significance alleleâ€šÃ„Ã¹, ClinVar (classified as uncertain significance by GeneDx, Invitae, Ambry Genetics and GeneKor; and as likely benign by Color) and LOVD 3.0 (observed 1x). The variant was identified in control databases in 10 of 245,814 chromosomes at a frequency of 0.00004 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the European population in 10 of 111,368 chromosomes (freq: 0.00009), but not in the African, Other, Latino, Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. The p.His1568 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
