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 significance, criteria provided, single submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	Oct 14, 2024	The ATM c.3378A>G (p.Lys1126=) synonymous variant has been reported in the published literature in individuals with breast cancer (PMID: 28779002 (2017), 29522266 (2018), 32885271 (2021)). The frequency of this variant in the general population, 0.00012 (15/128776 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using software algorithms for the prediction of the effect of nucleotide changes on splicing yielded predictions that this variant does not affect ATM mRNA splicing. Based on the available information, we are unable to determine the clinical significance of this variant. -
Uncertain significance, criteria provided, single submitter	clinical testing	Athena Diagnostics	Dec 20, 2023	Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is uninformative in assessment of its pathogenicity. (http://gnomad.broadinstitute.org) Computational tools yielded predictions that this variant is unlikely to have an effect on normal RNA splicing. -

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Jun 20, 2014	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. -

The ATM p.Lys1126= variant was identified in 1 of 26174 proband chromosomes (frequency: 0.00004) from individuals or families with breast cancer (Decker 2017). The variant was also identified in dbSNP (ID: rs149182949) as "With Likely benign allele" and ClinVar (classified as likely benign by Ambry Genetics, Invitae, Color Genomics, and Counsyl). The variant was not identified in the GeneInsight-COGR, Cosmic, or LOVD 3.0 databases. The variant was identified in control databases in 15 of 276638 chromosomes at a frequency of 0.00005 (Genome Aggregation Database Feb 27, 2017). The variant was observed in European population in 15 of 126256 chromosomes (freq: 0.0001), while the variant was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. The p.Lys1126= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. However, 2 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. 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. -
