Zero matches in 31,000+ myeloid patients.
That is the empirical finding across GENIE v19.0, cBioPortal (46 studies),
GDC (24 projects), ICGC, ClinVar, and 5 additional databases.
The proper math: Under independence, the expected frequency is ~~2.6×10-13 (1 in 3886.3 billion). But the mutations are not independent. We computed the pairwise-corrected estimate using all 10 gene-pair O/E ratios from Fisher's exact test 31
7 of 10 pairs are enriched (co-occur more than expected): SETBP1+EZH2 (O/E=4.96), SETBP1+PTPN11 (O/E=3.62), PTPN11+EZH2 (O/E=2.91), DNMT3A+IDH2 (O/E=2.74), DNMT3A+PTPN11 (O/E=1.95), IDH2+EZH2 (O/E=1.60), IDH2+PTPN11 (O/E=1.44), DNMT3A+EZH2 (O/E=1.10), DNMT3A+SETBP1 (O/E=1.06). The product of all 10 O/E ratios is 677×, meaning the combination is 677 times more likely than independence predicts.
Corrected estimate: ~1.7×10-10 (1 in 5.7 billion) 30

Oncogenic Convergence
Figure 3 | Oncogenic convergence on MYC.
Five driver mutations feed into six distinct pathways, all converging on MYC
transcription or protein stability.
Five mutations spanning six oncogenic axes:
epigenetic reprogramming (DNMT3A),
metabolic transformation (IDH2),
RAS-MAPK hyperactivation (PTPN11),
PP2A tumor suppressor loss (SETBP1),
PRC2 chromatin remodeling (EZH2),
and chromosomal instability (monosomy 7).
All converge on MYC. Each axis independently promotes
MYC transcription or protein stability through distinct
molecular mechanisms
