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

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Counsyl	Mar 15, 2017	- -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 20, 2023	This sequence change creates a premature translational stop signal (p.Gln2028*) in the ATM gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with ataxia-telangiectasia (PMID: 12552559, 22213089). ClinVar contains an entry for this variant (Variation ID: 231947). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -

Hereditary cancer-predisposing syndrome

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Jan 15, 2020	This variant changes 1 nucleotide in exon 41 of the ATM gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been identified in 1/251410 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of ATM function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 22, 2024	The p.Q2028* pathogenic mutation (also known as c.6082C>T), located in coding exon 40 of the ATM gene, results from a C to T substitution at nucleotide position 6082. This changes the amino acid from a glutamine to a stop codon within coding exon 40. This pathogenic mutation has been reported in multiple unrelated individuals diagnosed with ataxia-telangiectasia (Buzin CH et al. Hum. Mutat. 2003 Feb;21(2):123-31; Verhagen MM et al. Hum. Mutat. 2012 Mar;33(3):561-71). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
