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 glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 844 of the ATM protein (p.Gly844Glu). This variant is present in population databases (rs587781808, gnomAD 0.004%). This missense change has been observed in individual(s) with ATM-related cancers (PMID: 32383162). ClinVar contains an entry for this variant (Variation ID: 141514). 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: ATM c.2531G>A (p.Gly844Glu) results in a non-conservative amino acid change in 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 1.6e-05 in 251404 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.2531G>A has been reported in the literature in individuals affected with breast cancer without strong evidnce for causality (example: Hilbers_2020). These report(s) do not provide unequivocal conclusions about association of the variant with Prostate Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 32383162). ClinVar contains an entry for this variant (Variation ID: 141514). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The ATM c.2531G>A variant is predicted to result in the amino acid substitution p.Gly844Glu. This variant has been reported in individuals with breast cancer, an individual with epithelioid hemangioma, and a hepatic carcinoma specimen (Table 1, Subramaniam et al. 2018. PubMed ID: 29206716; Table S2, Hauke et al. 2018. PubMed ID: 29522266; Table S5, Decker et al. 2017. PubMed ID: 28779002; Table 3, Hilbers et al. 2020. PubMed ID: 32383162; Table 2, Howell et al. 2019. PubMed ID: 31173963). This variant is reported in 0.0035% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-108137962-G-A) and has conflicting interpretations of likely benign and uncertain significance in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/141514/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
