Across TCGA pan-cancer cohorts, GCDH Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated GCDH data layer compared with 23 for mass-spec protein and 8 for mass-spec protein.
The strongest signal is observed in stomach adenocarcinoma (STAD), where higher GCDH Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated GCDH expression acts as an unfavorable survival marker, although some lineages such as OV and SKCM show a favorable association.
STAD, COAD, and OV are the cancer types where GCDH Mutation most reproducibly stratifies survival.
