Across TCGA pan-cancer cohorts, KRTAP4-2 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of KRTAP4-2’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where KRTAP4-2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types KRTAP4-2 is over-expressed in tumor.
LUSC are the cancer types where KRTAP4-2 tumor–normal differential expression is most reproducible.
