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.6543G>T (p.Glu2181Asp) results in a conservative amino acid change located in the PIK-related kinase, FAT domain (IPR003151) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00015 in 251444 control chromosomes (gnomAD), predominantly at a frequency of 0.0022 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 the Breast Cancer phenotype (0.001), suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. In addition, the variant was found in 8/2559 African American women (allele frequency: 0.001563) older than 70 years of age, who had no history of cancer (FLOSSIES database). c.6543G>T has also been reported in the literature in individuals affected with Breast Cancer (e.g. Bernstein 2010, Haiman_2013, Tung 2016, Adedokun_2020, George_2021, Sandoval_2021). These reports do not provide unequivocal conclusions about association of the variant with Breast Cancer. Co-occurrences with a pathogenic variant ATM c.3049C>T (p.Gln1017X) has been seen multiple times in our lab, providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven ClinVar submitters have assessed the variant since 2014: five have classified the variant as of uncertain significance, and two as likely benign. Some submitters cite overlapping evidence utilized in the context of this evaluation. Based on the evidence outlined above, the variant was classified as benign. -

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. -

Review Status:no assertion criteria provided

Collection Method:clinical testing

The ATM c.6543G>T variant is predicted to result in the amino acid substitution p.Glu2181Asp. This variant has been previously reported in individuals with breast cancer (see for example Bernstein et al. 2010. PubMed ID: 20305132, Supplementary Table 2; Tung et al. 2016. PubMed ID: 26976419; Adedokun et al. 2020. PubMed ID: 31871109) and endometrial cancer (Lu et al. 2015. PubMed ID: 26689913, Supplementary Data 12). This variant is reported in 0.20% of alleles in individuals of African descent in gnomAD, an allele frequency that is likely too high for a disease causing variant. In ClinVar, this variant has conflicting interpretations regarding its pathogenicity, ranging from benign to uncertain significance (https://www.ncbi.nlm.nih.gov/clinvar/variation/127425/). Although we suspect this variant may be benign, at this time its clinical significance is uncertain due to the absence of conclusive functional and genetic evidence. -
