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]

Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The ATM p.Leu651= variant was identified in 14 of 14208 proband chromosomes (frequency: 0.001) from Japanese individuals or families with breast cancer and was present in 43 of 47462 control chromosomes (frequency: 0.0009) from healthy individuals (Momozawa 2018). The variant was also identified in dbSNP (ID: rs730881283) â€šÃ„ÃºWith Uncertain significance alleleâ€šÃ„Ã¹, ClinVar (classified as benign by GeneDx; as likely benign by Ambry Genetics, Invitae, Color, and Prevention Genetics; and as uncertain significance by Integrated Genetics/Laboratory Corporation of America), and LOVD 3.0 (1x as benign). The variant was identified in control databases in 22 of 277048 chromosomes at a frequency of 0.00008 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 1 of 24030 chromosomes (freq: 0.00004), Other in 1 of 6460 chromosomes (freq: 0.0002), Latino in 14 of 34416 chromosomes (freq: 0.0004), European Non-Finnish in 5 of 126592 chromosomes (freq: 0.00004), and South Asian in 1 of 30778 chromosomes (freq: 0.00003), while not observed in the Ashkenazi Jewish, East Asian, or European Finnish populations. The p.Leu651= 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) do not predict a difference in splicing. 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. -

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 01, 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. -
