Across TCGA pan-cancer cohorts, MUSK mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated MUSK data layer compared with 19 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher MUSK mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated MUSK expression acts as an unfavorable survival marker, although some lineages such as LUAD and PDAC show a favorable association.
LUAD, PDAC, and GBM are the cancer types where MUSK mass-spec protein most reproducibly stratifies survival.
