STX1B

Across TCGA pan-cancer cohorts, STX1B Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated STX1B 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 STX1B Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated STX1B expression acts as an unfavorable survival marker.

BLCA, HNSC, and UCEC are the cancer types where STX1B 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.
