Variant summary
Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000051.4(ATM):c.3935dupG(p.Glu1313ArgfsTer8) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,698 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. R1312R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Submissions by phenotype
Ataxia-telangiectasia syndrome Pathogenic:2
This sequence change creates a premature translational stop signal (p.Glu1313Argfs*8) 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: 232284). For these reasons, this variant has been classified as Pathogenic. -

Familial cancer of breast Pathogenic:2
This variant is considered pathogenic. This variant creates a frameshift predicted to result in premature protein truncation. -

Hereditary cancer-predisposing syndrome Pathogenic:2
The c.3935dupG pathogenic mutation, located in coding exon 25 of the ATM gene, results from a duplication of one nucleotide at position 3935, causing a translational frameshift with a predicted alternate stop codon (p.E1313Rfs*8). 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. -
This variant inserts 1 nucleotide in exon 26 of the ATM gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, this variant has not been reported in individuals affected with hereditary cancer in the literature. 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. -
not provided Pathogenic:1
Frameshift variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); Observed in individuals with a personal or family history consistent with pathogenic variants in this gene referred for genetic testing at GeneDx; Truncating variants in this gene are considered pathogenic by a well-established clinical consortium and/or database; This variant is associated with the following publications: (PMID: 27449771) -
