C21orf91

Across TCGA pan-cancer cohorts, C21orf91 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated C21orf91 data layer compared with 21 for mass-spec protein and 2 for mutation status.

The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher C21orf91 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated C21orf91 expression acts as an unfavorable survival marker, although some lineages such as GBM show a favorable association.

LSCC and GBM are the cancer types where C21orf91 mass-spec protein most reproducibly stratifies survival.

mass-spec protein 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.
