Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000051.4(ATM):βc.6839delβ(p.Gln2280ArgfsTer30) variant causes a frameshift change. The variant allele was found at a frequency of 0.00000657 in 152,108 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (β β ). Synonymous variant affecting the same amino acid position (i.e. Q2280Q) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Submissions by phenotype
Ataxia-telangiectasia syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 01, 2023 | This sequence change creates a premature translational stop signal (p.Gln2280Argfs*30) 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 not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 453644). For these reasons, this variant has been classified as Pathogenic. - |
Familial cancer of breast Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Jan 30, 2024 | This variant is considered pathogenic. This variant creates a frameshift predicted to result in premature protein truncation. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 02, 2021 | The c.6839delA pathogenic mutation, located in coding exon 46 of the ATM gene, results from a deletion of one nucleotide at nucleotide position 6839, causing a translational frameshift with a predicted alternate stop codon (p.Q2280Rfs*30). This alteration was previously reported in at least one individual from a cohort of 278 BRCA1/2-negative individuals with early-onset breast cancer via multiplex panel testing of 22 cancer susceptibility genes (Maxwell KN et al. Genet Med, 2015 Aug;17:630-8). 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. - |
