Across TCGA pan-cancer cohorts, NPAP1L RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of NPAP1L’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where NPAP1L RNA is more highly expressed in tumor relative to normal tissue. In most cancer types NPAP1L is over-expressed in tumor.
HNSC and LUSC are the cancer types where NPAP1L tumor–normal differential expression is most reproducible.
