Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Apr 27, 2017 | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. - |

Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 19, 2024 | This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 2287 of the ATM protein (p.Gly2287Glu). This variant is present in population databases (rs1800061, gnomAD 0.006%). This missense change has been observed in individual(s) with colorectal cancer (PMID: 28135145). ClinVar contains an entry for this variant (Variation ID: 185012). 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 glutamic acid 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 significance, criteria provided, single submitter | clinical testing | GeneDx | Aug 23, 2023 | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Identified in individuals with colorectal, breast, or other cancers (Yurgelun et al., 2017; Hauke et al., 2018; Lu et al., 2015); This variant is associated with the following publications: (PMID: 29522266, 28135145, 19781682, 28338653, 23532176, 11606401, 26689913) - |
not specified Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Genetic Services Laboratory, University of Chicago | Dec 01, 2020 | DNA sequence analysis of the ATM gene demonstrated a sequence change, c.6860G>A, in exon 47 that results in an amino acid change, p.Gly2287Glu. This sequence change has been previously described in a patient with colorectal cancer (PMID: 28135145). This sequence change has been described in the gnomAD database with a low population frequency of 0.0024% (dbSNP rs1800061). The p.Gly2287Glu change affects a moderately conserved amino acid residue located in a domain of the ATM protein that is known to be functional. The p.Gly2287Glu substitution appears to be benign using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Gly2287Glu change remains unknown at this time. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jun 29, 2020 | Variant summary: ATM c.6860G>A (p.Gly2287Glu) results in a non-conservative amino acid change located in the PIK-related kinase, FAT domain (IPR003151) 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 2.4e-05 in 251222 control chromosomes (genomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.6860G>A has been reported in the literature in individuals affected with kidney renal clear cell carcinoma and colorectal cancer (Lu_2015, Yurelun_2017). These reports do not provide unequivocal conclusions about association of the variant with Ataxia-Telangiectasia. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. - |
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Sep 12, 2022 | This missense variant replaces glycine with glutamic acid at codon 2287 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 or colorectal cancer (PMID: 28135145, 28338653, 33471991). This variant has been identified in 6/251222 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. - |
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 28, 2024 | 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. - |
Malignant tumor of breast Uncertain:1
Uncertain significance, no assertion criteria provided | clinical testing | Department of Pathology and Laboratory Medicine, Sinai Health System | - | The ATM p.Gly2287Glu variant was identified in 1 of 2116 proband chromosomes (frequency: 0.0005) from individuals or families with colorectal cancer (Yurgelun 2017). The variant was also identified in dbSNP (ID: rs1800061) as "With Uncertain significance allele", ClinVar (classified as uncertain significance by Invitae, Ambry Genetics, GeneDx, and two other submitters). The variant was not identified in LOVD 3.0. The variant was identified in control databases in 7 of 245976 chromosomes at a frequency of 0.00003 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the European population in 7 of 111490 chromosomes (freq: 0.00006), while the variant was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The p.Gly2287 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of 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. - |
