Across TCGA pan-cancer cohorts, SNORD115-41 RNA is linked to patient survival in 6 of 34 cancer types, making it the most broadly survival-associated SNORD115-41 data layer compared with 3 for mutation status.
The strongest signal is observed in thyroid carcinoma (THCA), where higher SNORD115-41 RNA is associated with worse overall survival. In most high-consensus cancer types, elevated SNORD115-41 expression acts as an unfavorable survival marker, although some lineages such as LGG show a favorable association.
THCA, UCEC, and KIRP are the cancer types where SNORD115-41 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.
