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:3

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Nov 13, 2023	This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 350 of the ATM protein (p.Ala350Val). This variant is present in population databases (rs375049090, gnomAD 0.006%). This missense change has been observed in individual(s) with breast cancer (PMID: 27553368, 35264596). ClinVar contains an entry for this variant (Variation ID: 236665). 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. -

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Jul 26, 2022	This missense variant replaces alanine with valine at codon 350 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 been reported with a PALB2 truncation (c.1633G>T, p.Glu545*) in an individual affected with breast cancer (PMID: 27553368). This variant has been identified in 2/251126 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 18, 2024	The p.A350V variant (also known as c.1049C>T), located in coding exon 7 of the ATM gene, results from a C to T substitution at nucleotide position 1049. The alanine at codon 350 is replaced by valine, an amino acid with similar properties. This alteration has been identified in individuals diagnosed with breast cancer (Pinto P et al. Breast Cancer Res Treat, 2016 Sep;159:245-56; Weitzel JN et al. Cancer, 2019 Aug;125:2829-2836; Guindalini RSC et al. Sci Rep, 2022 Mar;12:4190). 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 alteration remains unclear. -
