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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 2705 of the ATM protein (p.Val2705Ile). This variant is present in population databases (rs587779870, gnomAD 0.002%). This missense change has been observed in individual(s) with colorectal cancer and breast cancer (PMID: 25186627, 28135145). ClinVar contains an entry for this variant (Variation ID: 127454). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ATM protein function with a negative predictive value of 95%. 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. -

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. -

Variant summary: ATM c.8113G>A (p.Val2705Ile) results in a conservative amino acid change located in the ATM, catalytic domain (IPR044107) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251372 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.8113G>A has been observed in individual(s) affected with breast and/or ovarian, colorectal, and pancreatic cancers (example: Tung_2015, Tavera-Tapia_2017, Yurgelun_2017, Yu_2022), without strong evidence of causality. These report(s) do not provide unequivocal conclusions about association of the variant with Breast Cancer. At least one publication reports experimental evidence evaluating an impact on protein function. Specifically, a pKAP1 phospho-flow assay, calibrated using benign and pathogenic controls, was used to assess whether a variant was functionally neutral or deleterious and this assay demonstrated that the variant of interest was functionally neutral. The following publications have been ascertained in the context of this evaluation (PMID: 27913932, 25186627, 28135145, 35047863, 40105422). ClinVar contains an entry for this variant (Variation ID: 127454). Based on the evidence outlined above, the variant was classified as uncertain significance. -
