Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000051.4(ATM):c.4202T>A(p.Leu1401Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,459,494 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. L1401L) has been classified as Benign. Variant results in nonsense mediated mRNA decay.

Submissions by phenotype
Ataxia-telangiectasia syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 18, 2020 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). This variant has not been reported in the literature in individuals with ATM-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu1401*) in the ATM gene. It is expected to result in an absent or disrupted protein product. - |
Familial cancer of breast Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Jan 23, 2024 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |
