Pathogenic, criteria provided, single submitter | clinical testing | Baylor Genetics | Nov 03, 2022 | - - |
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Feb 06, 2024 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |
Hereditary cancer-predisposing syndrome Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 31, 2019 | The p.W2960* pathogenic mutation (also known as c.8879G>A), located in coding exon 61 of the ATM gene, results from a G to A substitution at nucleotide position 8879. This changes the amino acid from a tryptophan to a stop codon within coding exon 61. This alteration has been reported in 1 of 119 ataxia telangiectasia (A-T) chromosomes (Li A et al. Am. J. Med. Genet. 2000 May;92:170-7). In addition, this alteration was detected in a cohort of 221 patients with prostate cancer (Abida W et al. JCO Precis Oncol, 2017 Jul;2017:) as well as in a cohort of 54 patients with features suggestive of hereditary gastric cancer (Vogelaar IP et al. Eur. J. Hum. Genet., 2017 11;25:1246-1252). 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. - |
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Sep 12, 2023 | This variant changes 1 nucleotide in exon 62 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 ataxia-tel, gastric adenocarinoma, and prostate cancer (PMID: 10817650, 28825054, 28825054, 28875981). This variant has not been identified 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. - |
Ataxia-telangiectasia syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 04, 2022 | For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. ClinVar contains an entry for this variant (Variation ID: 429062). This premature translational stop signal has been observed in individual(s) with ataxia-telangiectasia and prostate cancer (PMID: 10817650, 28825054). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Trp2960*) 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). - |
