Across TCGA pan-cancer cohorts, OLIG2 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated OLIG2 data layer compared with 23 for mass-spec protein and 1 for mass-spec protein.

The strongest signal is observed in bladder urothelial carcinoma (BLCA), where higher OLIG2 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated OLIG2 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.

BLCA, READ, and UCEC are the cancer types where OLIG2 Mutation most reproducibly stratifies survival.

Mutation survival associations by lineage

Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
