PRKAR2A

Across TCGA pan-cancer cohorts, PRKAR2A Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated PRKAR2A data layer compared with 27 for mass-spec protein and 1 for mass-spec protein.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher PRKAR2A Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated PRKAR2A expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.

HNSC, PRAD, and STAD are the cancer types where PRKAR2A Mutation most reproducibly stratifies survival.

Mutation survival associations by lineage

Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
