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]

Collection Method: clinical testing

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.Leu895= variant was identified in 1 of 502 proband chromosomes (frequency: 0.002) from individuals or families with breast cancer or leukemia and was not identified in 396 control chromosomes from healthy individuals (Meier 2005, Austen 2008). The variant was also identified in the following databases: dbSNP (ID: rs3218687) as â€šÃ„ÃºWith other alleleâ€šÃ„Ã¹, in ClinVar (classified 2x as benign, 1x as likely benign), Clinvitae (classified 1x as benign, 1x as conflicting interpretations of pathogenicity), and Cosmic (1x as neutral). The variant was not identified in the MutDB, LOVD 3.0, or ATM-LOVD databases. The variant was identified in control databases in 1217 of 277096 (32 homozygous) chromosomes at a frequency of 0.004 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 1105 of 24026 chromosomes (freq: 0.046). The p.Leu895= 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. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
