Across TCGA pan-cancer cohorts, SNORD115-17 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated SNORD115-17 data layer compared with 4 for mass-spec protein.

The strongest signal is observed in bladder urothelial carcinoma (BLCA), where higher SNORD115-17 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated SNORD115-17 expression acts as an unfavorable survival marker.

BLCA and LUAD are the cancer types where SNORD115-17 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.
