Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000051.4(ATM):βc.2295delβ(p.Asn765LysfsTer12) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,660 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (β β ). Synonymous variant affecting the same amino acid position (i.e. N765N) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Likely pathogenic, criteria provided, single submitter | clinical testing | Counsyl | Mar 10, 2017 | - - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 09, 2024 | This sequence change creates a premature translational stop signal (p.Asn765Lysfs*12) 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: 230468). For these reasons, this variant has been classified as Pathogenic. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 16, 2020 | The c.2295delT pathogenic mutation, located in coding exon 14 of the ATM gene, results from a deletion of one nucleotide at nucleotide position 2295, causing a translational frameshift with a predicted alternate stop codon (p.N765Kfs*12). 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. - |
