Across TCGA pan-cancer cohorts, KCNJ1 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated KCNJ1 data layer compared with 22 for mass-spec protein and 1 for mass-spec protein.
The strongest signal is observed in kidney chromophobe (KICH), where higher KCNJ1 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated KCNJ1 expression acts as an unfavorable survival marker, although some lineages such as SKCM show a favorable association.
KICH, OV, and SKCM are the cancer types where KCNJ1 Mutation most reproducibly stratifies survival.
