Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000051.4(ATM):c.5870_5871del(p.Tyr1957CysfsTer7) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,246 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Y1957Y) 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 | Feb 13, 2018 | 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 been reported in individuals affected with breast cancer (PMID: 28724667). ClinVar contains an entry for this variant (Variation ID: 407654). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Tyr1957Cysfs*7) in the ATM gene. It is expected to result in an absent or disrupted protein product. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 29, 2016 | The c.5870_5871delAT pathogenic mutation, located in coding exon 38 of the ATM gene, results from a deletion of two nucleotides at positions 5870 to 5871, causing a translational frameshift with a predicted alternate stop codon. 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. - |
Familial cancer of breast Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Jan 26, 2024 | This variant is considered pathogenic. This variant creates a frameshift predicted to result in premature protein truncation. - |
