Across TCGA pan-cancer cohorts, PCDHGA2 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated PCDHGA2 data layer compared with 22 for mass-spec protein and 1 for mass-spec protein.
The strongest signal is observed in skin cutaneous melanoma (SKCM), where higher PCDHGA2 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated PCDHGA2 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
SKCM, CESC, and UCEC are the cancer types where PCDHGA2 Mutation most reproducibly stratifies survival.
