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]

Ataxia-telangiectasia syndrome Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeNov 24, 2023This sequence change replaces leucine, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 432 of the ATM protein (p.Leu432Gln). This variant is present in population databases (rs546621356, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with ATM-related conditions. This missense change has been observed to be homozygous or hemizygous in an individual who did not have the expected clinical features for that genetic result (Invitae). ClinVar contains an entry for this variant (Variation ID: 423251). 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 tolerated. 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. -

Uncertain significance, criteria provided, single submitterclinical testingGeneDxAug 17, 2022Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 33365035) -
Uncertain significance, criteria provided, single submitterclinical testingAthena DiagnosticsFeb 08, 2023Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is uninformative in assessment of its pathogenicity (http://gnomad.broadinstitute.org). Computational tools predict that this variant is damaging. -
Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2022The p.L432Q variant (also known as c.1295T>A), located in coding exon 9 of the ATM gene, results from a T to A substitution at nucleotide position 1295. The leucine at codon 432 is replaced by glutamine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Uncertain significance, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthAug 04, 2021This missense variant replaces leucine with glutamine at codon 432 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 1/250832 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. -
