The recorded framework is ClinGen RUNX1 VCEP v3.1.0. 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.
PM2_Supporting is met under the MM-VCEP specification. The grpmax filtering allele frequency (FAF) in gnomAD v4.1 is 3.259e-05 (0.00326%), which is below the VCEP threshold of ≤0.00005 (0.005%). The variant is present in ≥2,000 alleles tested (1,613,324 total alleles).
BP4 is met under the MM-VCEP specification for synonymous variants. The VCEP rule for synonymous variants requires SpliceAI ≤0.20. SpliceAI predicts no significant splice impact (max delta score = 0.02), which is well below the 0.20 threshold. Multiple lines of computational evidence suggest no impact on splicing.
Expert panel ClinGen Myeloid Malignancy Variant Curation Expert Panel classified as Likely benign.
BP7 is met under the MM-VCEP specification. The variant is a synonymous change (c.624C>T, p.Ala208=) located in exon 4, not within the last 3 nucleotides preceding the canonical donor splice site (c.722-724) or the first nucleotide following the canonical acceptor splice site (c.533). SpliceAI predicts no splice impact (max delta = 0.02 ≤ 0.20). Conservation data is no longer required per the VCEP v3.1.0 update.

NM_001001890.2:c.624C>T (p.Ala208=) is a synonymous variant in exon 4 of RUNX1 that does not alter the amino acid sequence.
This variant is present at extremely low frequency in gnomAD (v4.1 grpmax FAF = 3.259e-05, 53/1,613,324 alleles), meeting PM2_Supporting under the MM-VCEP specification (MAF ≤0.00005).
SpliceAI predicts no splice impact (max delta = 0.02), meeting BP4 (SpliceAI ≤0.20 for synonymous variants) under the MM-VCEP specification.
The variant meets BP7 as a synonymous change not located in the critical splice region (not in the last 3 nucleotides of exon 4 nor the first nucleotide after the acceptor site), with SpliceAI ≤0.20.
The ClinGen Myeloid Malignancy VCEP classified this variant as Likely Benign (ClinVar ID 532686, SCV001366061, reviewed by expert panel), consistent with the computed Tavtigian score of -1 (PM2_Supporting +1, BP4 -1, BP7 -1).
No pathogenic evidence was identified: no de novo occurrences (PS2/PM6), no probands with FPD/AML phenotype (PS4), no functional data demonstrating damaging effect (PS3), no cosegregation data (PP1), the variant lies outside the RHD (PM1 not met), and in silico predictions do not support pathogenicity (PP3 not met).
Population frequencies are too low to meet BA1 (>0.15%) or BS1 (0.015%-0.15%), but the variant is not absent from population databases.
BS3 could not be independently assessed as the primary functional assay data reviewed by the expert panel is not publicly accessible through ClinVar; however, the expert panel's Likely Benign classification implies functional evidence was not supportive of pathogenicity.
