OR2A4

Across TCGA pan-cancer cohorts, OR2A4 Mutation is linked to patient survival in 1 of 34 cancer types, making it a survival-associated OR2A4 data layer compared with 20 for mass-spec protein.

The strongest signal is observed in small cell lung cancer (SCLC), where higher OR2A4 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated OR2A4 expression acts as an unfavorable survival marker.

SCLC are the cancer types where OR2A4 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.
