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]

Variant summary: ATM c.2096A>G (p.Glu699Gly) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00019 in 251298 control chromosomes, predominantly at a frequency of 0.002 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 2 fold of the estimated maximal expected allele frequency for a pathogenic variant in ATM causing Breast Cancer phenotype (0.001), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. In addition, the variant was also reported in 9 African American individuals in the Flossies database (with a frequency of 0.003517) who were older than 70 years of age, and never had cancer, further suggesting a benign outcome for the variant. c.2096A>G has been reported in the literature in individuals affected with breast cancer, colorectal cancer, endometrial cancer, prostate cancer, pancreatic ductal adenocarcinoma and two individuals being tested for Lynch syndrome (e.g. Yurgelun_2015, Ring_2016, Tung_2016, Yurgelun_2017, Pearlman_2016, Tavtigian_2009, Chaffee_2018, Eygelaar_2022, Gheybi_2023). These reports however, do not provide unequivocal conclusions about association of the variant with Breast Cancer/Ataxia-Telangiectasia. 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: 28726808, 35039564, 36898365, 23555315, 17333338, 27978560, 27443514, 19781682, 26976419, 25980754, 28135145). ClinVar contains an entry for this variant (Variation ID: 181850). Based on the evidence outlined above, the variant was classified as likely benign. -

This alteration is classified as 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. -

Collection Method: clinical testing

The ATM p.Glu699Gly variant was identified in 4 of 9322 proband chromosomes (frequency: 0.0004) from individuals or families with endometrial cancer, breast cancer or Lynch syndrome and was present in 1 of 4490 control chromosomes (frequency: 0.0002) from healthy individuals (Ring 2016, Tavtigian 2009, Tung 2016, Yurgelun 2015). The variant was also identified in dbSNP (ID: rs147934285) as "With other allele", ClinVar (classified as benign by Ambry Genetics and EGL; as likely benign by GeneDx and two other submitters; and as uncertain significance by Invitae, Integrated Genetics/Laboratory Corporation of America and Counsyl). The variant was not identified in LOVD 3.0. The variant was identified in 65 of 276878 chromosomes at a frequency of 0.0002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 51 of 24024 chromosomes (freq: 0.002), Other in 1 of 6460 chromosomes (freq: 0.0002), Latino in 11 of 34400 chromosomes (freq: 0.0003), European in 2 of 126504 chromosomes (freq: 0.00002); it was not observed in the Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. The p.Glu699 residue is conserved in mammals but not in more distantly related organisms, and 5 of 5 computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume 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. -
