Across TCGA pan-cancer cohorts, SNORD115-15 RNA is linked to patient survival in 5 of 34 cancer types, making it the most broadly survival-associated SNORD115-15 data layer compared with 1 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher SNORD115-15 RNA is associated with worse overall survival. In most high-consensus cancer types, elevated SNORD115-15 expression acts as an unfavorable survival marker.
UCEC, STAD, and OV are the cancer types where SNORD115-15 RNA most reproducibly stratifies survival.
RNA 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.
