Across TCGA pan-cancer cohorts, IGHD5-24 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of IGHD5-24’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where IGHD5-24 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types IGHD5-24 is over-expressed in tumor.
LUSC, LUAD, and STAD are the cancer types where IGHD5-24 tumor–normal differential expression is most reproducible.
