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]

Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Jan 03, 2023	Variant summary: ATM c.3016A>G (p.Met1006Val) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.8e-05 in 251338 control chromosomes (gnomAD). This frequency is not higher than predicted for a pathogenic variant in ATM causing Ataxia-Telangiectasia (4.8e-05 vs 0.004), allowing no conclusion about variant significance. c.3016A>G has been reported in the literature as a VUS in individuals undergoing multigene cancer panel testing as well as in unaffected control cohorts (example, Mauer_2014, Tsaousis_2019, Tiao_2017). These report(s) do not provide unequivocal conclusions about association of the variant with Ataxia-Telangiectasia. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as VUS (n=5) and likely benign (n=2). Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1006 of the ATM protein (p.Met1006Val). This variant is present in population databases (rs139893395, gnomAD 0.009%). This missense change has been observed in individual(s) with personal and/or family history of cancer (PMID: 24113346, 31159747; Invitae). ClinVar contains an entry for this variant (Variation ID: 142162). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
