Across TCGA pan-cancer cohorts, MIR891A Mutation is linked to patient survival in 1 of 34 cancer types, making it the most broadly survival-associated MIR891A data layer compared with 1 for mass-spec protein.

The strongest signal is observed in lung adenocarcinoma (LUAD), where higher MIR891A Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated MIR891A expression acts as an unfavorable survival marker.

LUAD are the cancer types where MIR891A 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.
