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]

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Mar 06, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

The ATM p.Asp126Glu variant was identified in 15 of 1440 proband chromosomes (frequency: 0.01) from individuals or families with breast cancer (Broeks 2008, Gonzalez-Hormazabal 2008, Mangone 2015, Petereit 2013, Thorstenson 2001) and was present in 1 of 200 control chromosomes (frequency: 0.005) from healthy individuals (Mangone 2015). The variant was also identified in dbSNP (ID: rs2234997) as With other allele, ClinVar (classified as benign by Ambry Genetics, Emory Genetics, Prevention Genetics, Invitae; classified as likely benign by Illumina, IBRMDL, GSLUC), Cosmic (classified as neutral), MutDB (classified as Polymorphism), ATM-LOVD, databases. The variant was not identified in LOVD 3.0, databases. The variant was identified in control databases in 5588 (478 homozygous) of 276988 chromosomes at a frequency of 0.02 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017). The variant was identified in the following populations at a frequency greater than 1%: African in 4785 of 24012 chromosomes (freq: 0.199), Ashkenazi Jewish* in 143 of 10146 chromosomes (freq: 0.014), Latino in 396 of 34384 chromosomes (freq: 0.012), Other in 71 of 6456 chromosomes (freq: 0.011). The p.Asp126 residue is conserved in in mammals but not in more distantly related organisms however computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. The variant is located with the Telomere-length maintenance and DNA damage repair functional domain increasing the likelihood that it may have clinical significance. ATM D126E genotypes, had a mild effect on survival, but the differences did not reach the level of statistical significance (Li 2006). In addition, the variant lead to decreased DDR response and efficiency, which is associated with increased risk of developing lung cancer in African American women (Wallace 2014). In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
