Across TCGA pan-cancer cohorts, FXYD4 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated FXYD4 data layer compared with 16 for mass-spec protein and 1 for mass-spec protein.
The strongest signal is observed in rectum adenocarcinoma (READ), where higher FXYD4 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated FXYD4 expression acts as an unfavorable survival marker.
READ, LIHC, and UCEC are the cancer types where FXYD4 Mutation most reproducibly stratifies survival.
