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]

Review Status:no assertion criteria provided

Collection Method:clinical testing

The ATM c.3285-15C>T variant was not identified in the literature nor was it identified in the following databases: GeneInsight-COGR, Cosmic, MutDB, LOVD 3.0, or ATM-LOVD. The variant was identified in dbSNP (ID: rs770928986) as "With Benign allele", ClinVar (1x benign, 1x likely benign), and Clinvitae (1x benign). The variant was identified in control databases in 15 of 238752 chromosomes at a frequency of 0.00006 (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include Latino in 13 of 30880 chromosomes (freq: 0.0004) and European in 2 of 102914 chromosomes (freq: 0.00002), while the variant was not observed in the African, Other, Ashkenazi Jewish, East Asian, 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. -

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is considered benign. This variant is intronic and is not expected to impact mRNA splicing. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. -
