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:3

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Oct 11, 2017	The p.Met3011Val (rs372795527) has been reported in several individuals with breast carcinoma or a family history of breast cancer (Tavtigian, 2009; Teraoka, 2001; Thorstenson, 2003); however this variant has not been found associated with ataxia-telangiectasia nor primary immunodeficiency. This variant is listed in the Genome Aggregation Database (gnomAD) with an overall population frequency of 0.004 percent (identified on 11 out of 277,168 chromosomes), and has been reported to the ClinVar database as a variant of unknown significance (VariationID: 181906). The methionine at position 3,011 is moderately conserved considering 9 species (Alamut v2.10) and computational analyses of the p.Met3011Val variant on protein structure and function indicate a neutral effect (SIFT: tolerated, GVGD: class C0, PolyPhen-2: benign). Altogether, there is not enough evidence to classify the p.Met3011Val variant with certainty. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jul 10, 2024	Observed in individuals with a personal or family history of breast, prostate, or pancreatic cancer (PMID: 11505391, 12810666, 19781682, 33436325, 35047863); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 12810666, 11505391, 19781682, 26689913, 27200287, 25742471, 29641532, 30197789, 33436325, 35047863, 25148578, 37450374, 34482403, 23532176, 34262154) -

Familial cancer of breast

Uncertain:2Benign:1

Likely benign, criteria provided, single submitter	clinical testing	Myriad Genetics, Inc.	Jun 24, 2024	This variant is considered likely benign. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. -
Uncertain significance, criteria provided, single submitter	clinical testing	Baylor Genetics	Feb 28, 2024	- -
Uncertain significance, criteria provided, single submitter	clinical testing	St. Jude Molecular Pathology, St. Jude Children's Research Hospital	Dec 28, 2022	The ATM c.9031A>G (p.Met3011Val) missense change has a maximum subpopulation frequency of 0.0077% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect of this variant on protein function, and to our knowledge functional studies have not been performed. This variant has been reported in individuals with a personal and/or family history of breast and/or cancer (PMID: 11505391, 12810666, 19781682). It is absent in a database of women older than 70 years of age who have never had cancer (FLOSSIES database, https://whi.color.com/). To our knowledge, this variant has not been reported in individuals with ataxia telangiectasia. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Ataxia-telangiectasia syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 31, 2022	This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 3011 of the ATM protein (p.Met3011Val). This variant is present in population databases (rs372795527, gnomAD 0.008%). This missense change has been observed in individual(s) with breast cancer, glioblastoma multiforme and prostate cancer (PMID: 11505391, 12810666, 19781682, 26689913, 33436325). ClinVar contains an entry for this variant (Variation ID: 181906). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Dec 14, 2022	This missense variant replaces methionine with valine at codon 3011 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. This variant has been reported in individuals affected with breast cancer or prostate cancer (PMID: 11505391, 19781682, 33436325). This variant has been identified in 11/282840 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	Nov 09, 2022	The p.M3011V variant (also known as c.9031A>G), located in coding exon 62 of the ATM gene, results from an A to G substitution at nucleotide position 9031. The methionine at codon 3011 is replaced by valine, an amino acid with highly similar properties. In one study, this alteration, which is located in the kinase domain, was found in 1 of 142 breast cancer cases diagnosed before age 45 and not in any of the 81 controls (Teraoka SN et al. Cancer. 2001 Aug;92(3):479-87). A second study found this alteration in 1 of 270 breast and/or ovarian cancer families (Thorstenson YR et al. Cancer Res. 2003 Jun;63(12):3325-33). Another study found this alteration in 2 of 4112 breast cancer cases and in 0 of 2399 controls pooled from multiple studies (Tavtigian SV et al. Am. J. Hum. Genet. 2009 Oct;85(4):427-46). This alteration was also reported in 1/5560 prostate cancer cases and in 0/3353 controls of European ancestry (Karlsson Q et al. Eur Urol Oncol, 2021 08;4:570-579). 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. -

Variant summary: ATM c.9031A>G (p.Met3011Val) results in a conservative amino acid change located in the Phosphatidylinositol 3-/4-kinase, catalytic domain (IPR000403) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4e-05 in 251442 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in ATM causing Breast Cancer (4e-05 vs 0.001), allowing no conclusion about variant significance. c.9031A>G has been reported in the literature in individuals in individuals affected with or without a family history of Breast Cancer (e.g. Tavtigian_2009, Teraoka_2001, Thorstenson_2003) and Prostate Cancer (e.g. Karlsson_2020). These reports do not provide unequivocal conclusions about association of the variant with Breast Cancer. At-least one co-occurrence with another pathogenic variant has been observed at our laboratory (APC c.487C>T, p.Gln163Ter), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 27200287, 30197789, 33436325, 26689913, 25148578, 19781682, 11505391, 12810666). ClinVar contains an entry for this variant (Variation ID: 181906). Based on the evidence outlined above, the variant was classified as VUS-possibly benign. -

The ATM c.9031A>G variant is predicted to result in the amino acid substitution p.Met3011Val. This variant has been reported in multiple individuals with various cancers including breast, prostate, melanoma, and spinal chordoma (see for example, Table1, Teraoka et al. 2001. PubMed ID: 11505391; Table S4, Karlsson et al. 2021. PubMed ID: 33436325; Table S4, Siroy et al. 2014. PubMed ID: 25148578; Aleksic et al. 2016. PubMed ID: 27200287). This variant is reported in 0.0077% of alleles in individuals of European (non-Finnish) descent in gnomAD. This variant has been classified as uncertain by other institutions in the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/181906/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
