Across TCGA pan-cancer cohorts, IGHVII-53-1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of IGHVII-53-1’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where IGHVII-53-1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types IGHVII-53-1 is over-expressed in tumor.
LUSC and HNSC are the cancer types where IGHVII-53-1 tumor–normal differential expression is most reproducible.
