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]

clinical testing

Department of Pathology and Laboratory Medicine, Sinai Health System

The ATM p.Arg2034Gln variant was identified in the literature in a pooled case control study of 8224 breast cases and 4798 control cases and was identified in 1 control case (Tavtigian 2009). The variant was identified in the following databases: dbSNP (ID: rs3218670) as â€šÃ„ÃºWith Uncertain significance alleleâ€šÃ„Ã¹, in ClinVar (classified as uncertain significance by GeneDx, Ambry Genetics, Invitae and Color Genomics Inc.), Clinvitae (3x), and was not identified in the COGR, Cosmic, MutDB, LOVD 3.0. The variant was also identified in control databases in 37 of 277100 chromosomes at a frequency of 0.0001 (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: African in 1 of 24028 chromosomes (freq: 0.00004), Latino in 1 of 34410 chromosomes (freq: 0.00003), European Non-Finnish in 3 of 126644 chromosomes (freq: 0.00002), East Asian in 14 of 18836 chromosomes (freq: 0.0007), Finnish in 1 of 25794 chromosomes (freq: 0.00004), and South Asian in 17 of 30776 chromosomes (freq: 0.0006); it was not observed in the Other and Ashkenazi Jewish populations. The p.Arg2034 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the Gln variant impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and 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 the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
