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]

The p.M1830T variant (also known as c.5489T>C), located in coding exon 35 of the ATM gene, results from a T to C substitution at nucleotide position 5489. The methionine at codon 1830 is replaced by threonine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -

This missense variant replaces methionine with threonine at codon 1830 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 ATM-related disorders in the literature. This variant has been identified in 10/282110 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. -

Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1830 of the ATM protein (p.Met1830Thr). This variant is present in population databases (rs145812395, gnomAD 0.04%). 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: 127408). 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. -

ATM NM_000051.3 exon 36 p.Met1830Thr (c.5489T>C): This variant has not been reported in the literature but is present in 0.04% (10/24952) of African alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/11-108173749-T-C?dataset=gnomad_r2_1). This variant is present in ClinVar (Variation ID:127408). Evolutionary conservation suggests that this variant may not impact the protein; computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

The ATM c.5489T>C; p.Met1830Thr variant (rs145812395), to our knowledge, is not reported in the medical literature but is reported in the ClinVar database (Variation ID: 127408). This variant is found in the general population with an overall allele frequency of 0.004% (10/282110 alleles) in the Genome Aggregation Database. The methionine at codon 1830 is weakly conserved, but computational analyses (SIFT: Damaging, PolyPhen-2: Benign) predict conflicting effects of this variant on protein structure/function. Due to limited information, the clinical significance of this variant is uncertain at this time. -

Variant summary: ATM c.5489T>C (p.Met1830Thr) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 250720 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.5489T>C has not been reported in the literature in individuals affected with Breast Cancer and no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 36117189, 36315919). ClinVar contains an entry for this variant (Variation ID: 127408). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance: Uncertain significance
Review Status: no assertion criteria provided
Collection Method: clinical testing

The ATM c.5489T>C variant is predicted to result in the amino acid substitution p.Met1830Thr. This variant has been reported as an polymorphism in a breast cancer cohort study (Table 2, Bozhanov et al. 2010. PubMed ID: 20177704). It is reported in 0.040% of alleles in individuals of African descent in gnomAD and is interpreted as uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/127408/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
