In his Int J Cancer editorial, @jeffreytownsend.bsky.social cautions that a pan-cancer co-mutation map can reflect tissue. Vaeyens et al. published their data, so we re-ran their BRAF/KRAS/EGFR calls within tumour types and against chance. Textbook exclusions hold; no co-occurrence does.

Bar chart. The 59 co-mutation calls Vaeyens et al. flag as significant, grouped by the direction each names and re-tested on the authors' data against chance within tumour types at the study's code threshold. Class exclusivities: 7 of 8 hold, 1 cannot be settled within tumour types. Variant exclusivities: 6 of 7 hold, 1 in the same direction at p below 0.05 only. Variant-pair exclusivities: 9 of 38 hold, 29 cannot be settled within tumour types. Co-occurrences: 0 of 6 hold; 4 are consistent with chance and 2 are found together less often than chance.

We checked our open co-mutation scan against SelectSim (@arvind-k-iyer.bsky.social @ciriellolab.bsky.social et al., Nat Genet 2026), using both methods' public files. Where both call a gene pair, the direction agrees: 159/161 on largely shared MSK patients, 115/118 at Dana-Farber, 34/34 in TCGA.

Chart comparing Cybergenic's co-alteration scan (snapshot of 3 October 2026) with SelectSim's published results (Iyer et al., Nature Genetics 2026, estimated FDR at most 0.25), for the gene pairs the scan keeps. Largely shared MSK patients: 203 pairs kept; SelectSim calls 159 the same direction, 2 the opposite, 42 not called. Dana-Farber patients: 182 kept; 115 same, 3 opposite, 64 not called. Same TCGA studies: 36 kept; 34 same, none opposite, 2 not called. When both methods call a pair, the direction agrees in 159 of 161, 115 of 118 and 34 of 34.

Lung cancer driver mutations that avoid each other, or travel together, in 6,575 MSK-IMPACT patients. EGFR and KRAS share 11 tumours where chance predicts 305; KEAP1 and STK11 share 130 where it predicts 42. Known biology, recovered under a burden-aware null. #bioinformatics #cancerresearch

Lollipop chart from the Cybergenic co-alteration dataset: tumours with driver mutations in both genes, observed versus expected by chance given each tumour's number of driver mutations, within detailed tumour types, in 6,575 MSK-IMPACT non-small cell lung cancer patients. Travel together (more than expected): KEAP1 and STK11, 130 vs 42; SMARCA4 and STK11, 79 vs 37; KRAS and STK11, 370 vs 222; KRAS and RBM10, 249 vs 166; KEAP1 and KRAS, 119 vs 81. Avoid each other (fewer than expected): BRAF and EGFR, 8 vs 32; BRAF and KRAS, 15 vs 60; KRAS and MET, 9 vs 36; EGFR and MET, 3 vs 24; ERBB2 and KRAS, 3 vs 32; EGFR and STK11, 5 vs 106; EGFR and KRAS, 11 vs 305; EGFR and KEAP1, 0 vs 31. Every pair q < 0.001.
