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.
The ATM VCEP supplementary functional data (Suppl_TableS1, PMID 40580951) classifies NM_000051.4:c.5600A>G (p.Q1867R) as 'Non-functional' with Medium-high confidence based on a combined function score of -2.05 integrating multiple functional predictors. This meets the VCEP PS3_Supporting threshold for a variant that fails to rescue an ATM-specific functional feature. No direct experimental rescue assay data (kinase activity or radiosensitivity) from the VCEP-approved functional studies (Mitui 2009, Barone 2009, Scott 2002) was identified for this exact variant.
NM_000051.4:c.5600A>G is present at an extremely low frequency in gnomAD v4.1 (AF = 1.8588e-06, 0.000186%, 3/1,613,944 alleles, 0 homozygotes). This is below the VCEP PM2_Supporting threshold of ≤0.001% (≤1e-5). The variant is absent from gnomAD v2.1 and gnomAD-Canada.
The ATM VCEP BP4 threshold for missense variants is REVEL ≤ 0.249. NM_000051.4:c.5600A>G (p.Q1867R) has a REVEL score of 0.088, meeting the BP4_Supporting threshold. Additionally, the SpliceAI max delta score is 0.10, which is ≤0.1, meeting the VCEP BP4 splicing threshold (no predicted splicing impact). BayesDel score of -0.34033 also supports a benign computational prediction.

Recorded SpliceAI maximum delta score: 0.100. Refer to the recorded PP3/BP4 rationale for interpretation.
4 Uncertain significance.
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 not previously been reported in somatic cancers (COSMIC).
This variant does not lie in a statistically significant hotspot.

NM_000051.4:c.5600A>G (p.Gln1867Arg) is a missense variant in exon 37 of ATM. It has been reported in ClinVar as a variant of uncertain significance (ClinVar ID 453589, 4 clinical laboratories).
This variant is present in gnomAD v4.1 at an extremely low allele frequency (AF = 1.86e-6, 3/1,613,944 alleles, 0 homozygotes) and is absent from gnomAD v2.1 and gnomAD-Canada, meeting the ATM VCEP PM2_Supporting threshold (≤0.001%).
The ATM VCEP supplementary functional data (Suppl_TableS1, PMID 40580951) classifies this variant as 'Non-functional' (combined score -2.05, Medium-high confidence), meeting PS3_Supporting per the VCEP framework for variants that fail to rescue ATM-specific functional features.
Multiple computational predictors suggest a benign effect: REVEL score 0.088 (meeting BP4_Supporting threshold ≤0.249), BayesDel -0.34033, AlphaMissense 0.0758. SpliceAI predicts no splicing impact (max delta 0.10, meeting BP4 splicing threshold ≤0.1).
No case-control studies, co-segregation data, or confirmed de novo observations have been identified for this variant. A ClinVar submission noting observation in trans with a pathogenic ATM variant in an A-T patient was not accompanied by peer-reviewed publication, precluding application of PM3.
The variant has not been reported in COSMIC and is not located in a statistically significant cancer hotspot residue.
