Across TCGA pan-cancer cohorts, IGHVII-46-1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of IGHVII-46-1’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where IGHVII-46-1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types IGHVII-46-1 is over-expressed in tumor, although a few such as COAD show the opposite, repressed pattern.
LUAD and COAD are the cancer types where IGHVII-46-1 tumor–normal differential expression is most reproducible.
