XIAP

Across TCGA pan-cancer cohorts, XIAP Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated XIAP data layer compared with 24 for mass-spec protein and 6 for mass-spec protein.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher XIAP Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated XIAP expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.

HNSC and UCEC are the cancer types where XIAP 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.
