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]

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Variant summary: ATM c.2466+7A>G alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00032 in 275780 control chromosomes, predominantly at a frequency of 0.0046 within the East Asian subpopulation in the gnomAD database. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 4.6 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 East Asian origin. To our knowledge, no occurrence of c.2466+7A>G in individuals affected with Breast Cancer and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -

Collection Method: clinical testing

The ATM c.2466+7A>G variant was not identified in the literature nor was it identified in the following databases: GeneInsight-COGR, Cosmic, MutDB, or LOVD 3.0. The variant was identified in dbSNP (ID: rs55812024) as "With Benign allele", ClinVar (1x benign, 1x likely benign), and Clinvitae databases. The variant was identified in control databases in 89 of 275780 chromosomes at a frequency of 0.0003 (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include Latino in 3 of 34346 chromosomes (freq: 0.00009) and East Asian in 86 of 18806 chromosomes (freq: 0.005), while the variant was not observed in the African, Other, European, Ashkenazi Jewish, Finnish, or South Asian populations. 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. 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. -
