0 matches in 31,000+ myeloid patients across 10+ databases. Pairwise-corrected expected frequency: 1 in 5.7 billion (677× O/E correction applied).

In 2013, your laboratory identified recurrent SETBP1 mutations in the SKI-homologous degron motif of atypical CML patients (Piazza et al. 2013), a finding independently confirmed by Makishima et al. (2013). This portal extends the SETBP1 partnership landscape to 20,820 myeloid patients in GENIE v19.0 (AACR GENIE 2017), integrating co-occurrence statistics with protein language model scoring (Lin et al. 2023), molecular docking, and formal ACMG evidence aggregation across 15 computational tools. Five driver mutations spanning six oncogenic axes, zero quintuple matches in 31,000+ screened patients, and a pairwise-corrected expected frequency of 1 in 1.9 billion.

Progressive Mutation Filtering

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× — the combination is 677 times more likely than independence predicts.

Oncogenic Convergence

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 converging on MYC. Each axis independently promotes MYC transcription or protein stability through distinct molecular mechanisms 12
