Across TCGA pan-cancer cohorts, CARD18 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of CARD18’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where CARD18 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types CARD18 is over-expressed in tumor.
LUSC, LIHC, and LUAD are the cancer types where CARD18 tumor–normal differential expression is most reproducible.
