Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BP4_Strong
The NM_000051.4(ATM):c.1775G>A(p.Ser592Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000411 in 1,460,630 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S592G) has been classified as Uncertain significance.

Ataxia-telangiectasia syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 01, 2022 | This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 592 of the ATM protein (p.Ser592Asn). This variant is present in population databases (rs776911505, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 453381). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ATM 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. - |

not provided Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Oct 01, 2019 | In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge - |
Uncertain significance, criteria provided, single submitter | clinical testing | Quest Diagnostics Nichols Institute San Juan Capistrano | Aug 23, 2016 | The frequency of this variant in the general population, 0.00017 (6/34542 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported in unaffected individuals (PMID: 31206626 (2019)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. - |
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Apr 14, 2021 | This missense variant replaces serine with asparagine at codon 592 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 6/250408 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 14, 2024 | 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. - |
Familial cancer of breast Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Baylor Genetics | Aug 30, 2020 | This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. - |
