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	Labcorp Genetics (formerly Invitae), Labcorp	Dec 23, 2022	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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 127350). This variant has not been reported in the literature in individuals affected with ATM-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 817 of the ATM protein (p.Asp817Val). -

Variant summary: ATM c.2450A>T (p.Asp817Val) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251016 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.2450A>T has been reported in the literature in prostate cancer biopsies (Mateo_2020), but it has also been reported in healthy controls (PMID: 33471991, LOVD). These reports do not provide unequivocal conclusions about association of the variant with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

This variant is denoted ATM c.2450A>T at the cDNA level, p.Asp817Val (D817V) at the protein level, and results in the change of an Aspartic Acid to a Valine (GAT>GTT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. ATM Asp817Val was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This variant is a non-conservative substitution in which a negative polar amino acid is replaced with a neutral non-polar one, altering a position that is well conserved throughout evolution and is not located in a known functional domain. Multiple in silico algorithms predict that this variant may be damaging to protein structure and function. Based on the currently available information, we consider ATM Asp817Val to be a variant of uncertain significance. -

The p.D817V variant (also known as c.2450A>T), located in coding exon 15 of the ATM gene, results from an A to T substitution at nucleotide position 2450. The aspartic acid at codon 817 is replaced by valine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
