Across TCGA pan-cancer cohorts, SPNS1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated SPNS1 data layer compared with 28 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher SPNS1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated SPNS1 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LUAD show a favorable association.
CCRCC, HNSC, and UCEC are the cancer types where SPNS1 mass-spec protein most reproducibly stratifies survival.
