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]

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 14, 2019	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. -

Likely benign, criteria provided, single submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	Nov 22, 2024	*only use if reclassification to LB is not approved* The ATM c.6998C>T (p.Thr2333Ile) variant has been reported in the published literature in individuals with lung adenocarcinoma (PMID: 28843361 (2017)) and breast cancer (PMID: 35957908 (2022)). The frequency of this variant in the general population, 0.00084 (21/24960 chromosomes in African/African American subpopulation (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is higher than would generally be expected for pathogenic variants in this gene. 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. -
Likely benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Jan 02, 2024	Variant summary: ATM c.6998C>T (p.Thr2333Ile) results in a non-conservative amino acid change located in the PIK-related kinase, FAT domain (IPR003151) of the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.8e-05 in 251024 control chromosomes, predominantly at a frequency of 0.00074 within the African or African-American subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in ATM causing Breast Cancer (4.8e-05 vs 0.001), allowing no conclusion about variant significance. However, this variant has also been reported in 6/2559 African American women (i.e. with an allele frequency of 0.0012) who were older than age 70 and cancer free (FLOSSIES database), supporting a benign role for the variant. The variant, c.6998C>T, has been reported in the literature in an individuals affected with Lung adenocarcinoma or breast/ovarian cancer (Parry_2017, Gifoni_2022). This report does not provide unequivocal conclusions about association of the variant with Breast Cancer or 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: 35957908, 28843361). Seven submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 and classified this variant as uncertain significance (n=3), likely benign (n=3) and benign (n=1). Based on the evidence outlined above, the variant was classified as likely benign. -
