Across TCGA pan-cancer cohorts, HEPN1 RNA is linked to patient survival in 1 of 34 cancer types, making it a survival-associated HEPN1 data layer compared with 3 for mutation status.
The strongest signal is observed in small cell lung cancer (SCLC), where higher HEPN1 RNA is associated with worse disease-free survival. In most high-consensus cancer types, elevated HEPN1 expression acts as an unfavorable survival marker.
SCLC are the cancer types where HEPN1 RNA most reproducibly stratifies survival.
