RCV000169516 | SCV000260922 | pathogenic | Ataxia-telangiectasia syndrome | 2024-01-21 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Trp2769*) 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 (rs778269655, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with ataxia-telangiectasia (PMID: 8845835). ClinVar contains an entry for this variant (Variation ID: 189104). For these reasons, this variant has been classified as Pathogenic. |

RCV000579481 | SCV000682476 | pathogenic | Hereditary cancer-predisposing syndrome | 2023-03-06 | criteria provided, single submitter | clinical testing | This variant changes 1 nucleotide in exon 57 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 reported in individuals affected with breast cancer (PMID: 26786923), pancreatic cancer (PMID: 33436325), and in the compound heterozygous state with a second ATM mutation in individuals affected with ataxia-telangiectasia (PMID: 8845835, 22649200). This variant has been identified in 2/251376 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. |
Ambry Genetics | RCV000579481 | SCV001189935 | pathogenic | Hereditary cancer-predisposing syndrome | 2023-10-20 | criteria provided, single submitter | clinical testing | The p.W2769* pathogenic mutation (also known as c.8307G>A), located in coding exon 56 of the ATM gene, results from a G to A substitution at nucleotide position 8307. This changes the amino acid from a tryptophan to a stop codon within coding exon 56. This mutation has been identified in several individuals with Ataxia-telangiectasia (AT) who also carried another mutation in the ATM gene (Gilad S, et al. Hum. Mol. Genet. 1996;5(4):433-9; Jackson TJ et al. Dev. Med. Child Neurol. 2016 07;58:690-7; Ambry internal data). This alteration has also been reported in at least one subject in a study of 13087 breast cancer cases and 5488 control individuals in the UK (Decker B et al. J. Med. Genetic. 2017 11;54:732-741) and was identified in 2/2000 Australian breast or ovarian cancer patients and 0/1997 controls undergoing multigene panel testing for hereditary cancer risk (Thompson ER et al, J. Clin. Oncol. 2016 May;34:1455-9). 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. |

RCV000169516 | SCV002598754 | pathogenic | Ataxia-telangiectasia syndrome | 2022-09-12 | criteria provided, single submitter | clinical testing | Variant summary: ATM c.8307G>A (p.Trp2769X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 8e-06 in 251376 control chromosomes (gnomAD). c.8307G>A has been reported in the literature in individuals affected with breast cancer or prostate cancer (Decker_2017, Nguyen-Dumont_2020). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six ClinVar submitters (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
