OR4K5

Across TCGA pan-cancer cohorts, OR4K5 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated OR4K5 data layer compared with 7 for mass-spec protein.

The strongest signal is observed in lung squamous cell carcinoma (LUSC), where higher OR4K5 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated OR4K5 expression acts as an unfavorable survival marker, although some lineages such as SCLC show a favorable association.

LUSC and SCLC are the cancer types where OR4K5 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.
