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]

Ambry Genetics

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.W2344* pathogenic mutation (also known as c.7032G>A), located in coding exon 47 of the ATM gene, results from a G to A substitution at nucleotide position 7032. This changes the amino acid from a tryptophan to a stop codon within coding exon 47. 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. -

Color Diagnostics, LLC DBA Color Health

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant changes 1 nucleotide in exon 48 of the ATM gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, this variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 3/251086 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. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Trp2344*) 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 0.009%). This premature translational stop signal has been observed in individual(s) with ATM-related disease (Invitae). ClinVar contains an entry for this variant (Variation ID: 429080). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The ATM c.7032G>A (p.Trp2344*) variant causes the premature termination of ATM protein synthesis. This variant has been reported in the published literature in an individual with ovarian cancer (PMID: 28888541 (2017)). This variant has been identified as homozygous in at least one individual with ataxia-telangiectasia (Invitae, personal communication regarding ClinVar ID: 429080). The frequency of this variant in the general population, 0.000087 (3/34584 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic. -
