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.
This variant is present at very low frequency in gnomAD v4.1 (total AF = 0.00031%, 5/1,611,834 alleles, 0 homozygotes), meeting the VCEP PM2_Supporting threshold of ≤0.001%. Observed predominantly in the East Asian population (sub-population AF = 0.011%). Per VCEP guidance, PM2 is not considered conflicting evidence for variants that otherwise are likely benign/benign.
SpliceAI predicts no splice impact (max delta = 0.0), meeting the VCEP BP4 threshold of SpliceAI ≤0.1 for splicing prediction. Multiple lines of computational evidence (SpliceAI) suggest no impact on splicing. REVEL not available for synonymous variants. Note: BP4 and BP7 both draw from the same underlying observation of absent splice impact; applied together they may overlap.
NM_000051.4:c.7974T>C is a synonymous variant p.(Asn2658=) located in exon 54 (c.7939-c.8077). The variant is 35 nucleotides downstream of the acceptor site and 103 nucleotides upstream of the donor site, placing it well outside the VCEP-defined splice consensus regions (+7 donor, -21 acceptor). SpliceAI predicts no splice impact (max delta = 0.0). VCEP BP7 criteria for synonymous variants are met.
Richards et.al., 2015 - Combining rules v1.5.0 criteria-combination framework: matched Rule19 (Benign.Supporting >=2) with applied criteria: PM2 supporting, BP4 supporting, BP7 supporting; maps to Likely Benign.

NM_000051.4:c.7974T>C is a synonymous variant p.(Asn2658=) in ATM exon 54, located well outside the canonical splice consensus regions.
SpliceAI predicts no splice impact (max delta score = 0.00).
This variant is present in gnomAD v4.1 at very low frequency (total AF = 0.00031%, 5/1,611,834 alleles, 0 homozygotes), highest in East Asian population (sub-population AF = 0.011%).
ClinVar reports this variant as Likely benign (4 clinical laboratories) and Benign (1 laboratory); review status: criteria provided, single submitter (ClinVar Variation ID: 414583).
The ClinGen HBOP VCEP supplementary table (PMID:40580951, Table S1) classifies this variant as Likely benign with an eDA score of 3.10e-06.
BP7_Supporting is met: synonymous variant outside donor +7 and acceptor -21 splice regions with no predicted splice impact (SpliceAI = 0.0).
BP4_Supporting is met: no predicted impact via splicing (SpliceAI max delta = 0.0 ≤ 0.1). Note partial overlap with BP7.
PM2_Supporting is met: gnomAD v4.1 total allele frequency (0.00031%) is ≤ 0.001% VCEP threshold. Per VCEP guidance, PM2 is not considered conflicting evidence for variants that otherwise are likely benign/benign.
No pathogenic criteria beyond PM2_Supporting are met. Multiple benign supporting criteria (BP7, BP4) are met with no conflicting pathogenic evidence per VCEP PM2 guidance.
The ClinGen HBOP Expert Panel classification from the VCEP supplementary table is Likely benign, which is concordant with the evidence-based assessment.
