About ATM

No gene-level summary was recorded for this case.

LYFE Sciences is an AI system, and it can make mistakes. Criteria may be applied incorrectly, sources may be misread, and a confident-looking classification can still be wrong. Double-check every criterion and its underlying evidence before relying on any call.
01The reasoning

How it was classified

The recorded framework is ClinGen ATM VCEP v1.5. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.

Recorded applied criteria

The applied criteria and their strengths are shown as assessed under the stated framework.

Pathogenic evidence criteria: 2 Benign evidence criteria: 2
Pathogenic criteria applied · 2
PM2Supporting
PM2 · supporting

This variant is present in gnomAD v4.1 at an extremely low frequency (AF=1.86e-06; 3/1,613,480 alleles, 0 homozygotes; grpmax FAF=6.8e-07). Per ATM VCEP v1.5, frequency ≤0.001% in gnomAD v4 qualifies for PM2_Supporting.

PP3Supporting
PP3 · supporting

SpliceAI predicts a possible splicing impact (max delta score = 0.24). Per ATM VCEP v1.5, SpliceAI ≥0.2 qualifies for PP3_Supporting for missense variants via the splicing prediction route. The REVEL score (0.054) does NOT independently support PP3 via the missense pathway (threshold >0.7333).

Functional assay data curated by the ATM HBOP VCEP (Suppl_TableS1, based on kinase activity assays: Mitui 2009 PMID 18634022, Barone 2009 PMID 19431188; and radiosensitivity assays: Mitui 2009, Scott 2002 PMID 11805335) classify NM_000051.4:c.4997A>C (p.E1666A) as 'Functional' with High confidence (combined score 0.456). The variant rescues both ATM-specific kinase activity (phosphorylation of ATM targets) and cellular radiosensitivity, satisfying the VCEP BS3_Moderate threshold: variant rescues both an ATM-specific feature AND radiosensitivity.

BP4Supporting
BP4 · supporting

The REVEL score for this variant is 0.054, which is ≤0.249, meeting the ATM VCEP BP4_Supporting threshold for missense variants. Multiple in silico predictors support a benign effect: REVEL 0.054, BayesDel -0.367, EVE 0.058, AlphaMissense 0.1033. The SpliceAI delta (0.24) does NOT support BP4 via the splicing route (threshold ≤0.1).

NM_000051.4:c.4997A>C (p.Glu1666Ala) is a missense variant at an extremely low population frequency (gnomAD v4.1 AF = 1.86e-06, 3/1,613,480 alleles).

Functional assay data curated by the ClinGen HBOP VCEP demonstrate that p.Glu1666Ala rescues both ATM kinase activity and cellular radiosensitivity to wild-type levels, consistent with a benign functional effect (BS3_Moderate).

Multiple in silico predictors support a benign effect: REVEL 0.054 (≤0.249, BP4_Supporting), BayesDel -0.367, EVE 0.058, AlphaMissense 0.1033.

SpliceAI predicts a possible splicing impact (max delta 0.24, ≥0.2) qualifying for PP3_Supporting under the VCEP splicing prediction rule, though this is modestly above threshold and conflicts with the benign in silico and functional evidence.

The variant is absent from COSMIC and no case-control or segregation studies are available. Six publications provided by ClinVar were reviewed in full text; none mention NM_000051.4:c.4997A>C specifically.
