The recorded framework is ClinGen ATM VCEP v1.5.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
No pathogenic criterion marked as applied in the recorded assessment.
ATM VCEP applies BP4_Supporting when SpliceAI predicts no splicing impact (max delta ≤0.1). SpliceAI predicts no significant splice impact for c.7381C>T (max delta score = 0.07), meeting the VCEP BP4 threshold for absence of predicted splicing disruption. The REVEL score of 0.707 does not meet the missense BP4 threshold (≤0.249), but BP4 is independently satisfied by the splicing computational evidence.
Richards et.al., 2015 - Combining rules v1.5.0 criteria-combination framework was evaluated deterministically with applied criteria: BP4 supporting; no rule matched the adjudicated criteria.

OncoKB did not identify variant-specific reviewed functional evidence for this variant; gene-level curated context is available for reviewer follow-up. ATM, a kinase involved in the DNA damage response, is mutated in various solid and hematologic malignancies.
This variant has previously been reported in somatic cancers (COSMIC; COSV53748241, n = 2 times).
This variant does not lie in a statistically significant hotspot.

NM_000051.4:c.7381C>T (p.Arg2461Cys) is a missense variant in ATM, a gene where loss of function is an established mechanism for Ataxia-Telangiectasia (AR) and heterozygous variants confer moderate risk for breast and other cancers (AD).
This variant is not a null variant and SpliceAI predicts no splicing impact (max delta 0.07); PVS1 is not applicable per the ATM VCEP v1.5.0 decision tree.
This variant is present in gnomAD v4.1 at an overall allele frequency of 0.00613% (99/1,614,160 alleles; 0 homozygotes) with a grpmax filtering AF of 0.039%. The frequency exceeds the PM2_Supporting threshold (≤0.001%) but does not reach BS1 (>0.05%) or BA1 (>0.5%).
In silico predictions are inconclusive: REVEL score of 0.707 falls between the PP3 threshold (>0.7333) and BP4 missense threshold (≤0.249), neither meeting nor refuting pathogenicity. However, SpliceAI predicts no splicing impact (max delta 0.07 ≤ 0.1), satisfying BP4_Supporting.
This variant has been reported in ClinVar (VCV000142541) with predominantly uncertain significance classifications (14 clinical laboratories), with a minority of likely benign (3) and benign (1) submissions. No expert panel classification is available.
Functional evidence from the VCEP-validated Barone 2009 (PMID:19431188) kinase assay suggests partial impairment of ATM autophosphorylation, potentially supporting PS3_Supporting, but full-text verification of the variant-specific result was not possible in this assessment. Human review is recommended.
No case-control study meeting PS4 criteria, no published segregation data for PP1, and no phased trans/cis data for PM3/BP2 were identified for this variant.
Applying the ATM VCEP v1.5.0 criteria combination rules (Richards et al. 2015), only BP4_Supporting is met with no pathogenic criteria satisfied. The variant is classified as a Variant of Uncertain Significance (VUS). If PS3_Supporting is confirmed upon human review of the functional data, the variant would remain VUS (1 pathogenic supporting + 1 benign supporting under Rule31).
