Across TCGA pan-cancer cohorts, SNORD115-27 RNA is linked to patient survival in 3 of 34 cancer types, making it the most broadly survival-associated SNORD115-27 data layer compared with 1 for mutation status.
The strongest signal is observed in stomach adenocarcinoma (STAD), where higher SNORD115-27 RNA is associated with worse overall survival. In most high-consensus cancer types, elevated SNORD115-27 expression acts as an unfavorable survival marker.
STAD, GBM, and LIHC are the cancer types where SNORD115-27 RNA most reproducibly stratifies survival.
