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]

Hereditary cancer-predisposing syndrome Uncertain:2

Color Diagnostics, LLC DBA Color Health
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This missense variant replaces cysteine with tyrosine at codon 458 of the ATM protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been observed in the compound heterozygous in an individual affected with mild ataxia-telangiectasia (PMID: 32775531). This variant has not been identified 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. -

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

The p.C458Y variant (also known as c.1373G>A), located in coding exon 9 of the ATM gene, results from a G to A substitution at nucleotide position 1373. The cysteine at codon 458 is replaced by tyrosine, an amino acid with highly dissimilar properties. This variant has been identified with an ATM likely pathogenic variant in an individual with clinical features of ataxia-telangiectasia (Perez Maturo J et al. J Hum Genet, 2020 Oct;65:895-902; Perez Maturo J et al. Mov Disord Clin Pract, 2020 Aug;7:727-729; Salinas V et al. Am J Med Genet C Semin Med Genet, 2020 12;184:876-884). 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. -

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

This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 458 of the ATM protein (p.Cys458Tyr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with ataxia-telangiectasia (PMID: 32488064, 32775531, 33084218). ClinVar contains an entry for this variant (Variation ID: 524415). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
