CHRNA9

Across TCGA pan-cancer cohorts, CHRNA9 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated CHRNA9 data layer compared with 28 for mass-spec protein.

The strongest signal is observed in prostate adenocarcinoma (PRAD), where higher CHRNA9 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated CHRNA9 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.

PRAD, UCEC, and ACC are the cancer types where CHRNA9 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.
