Across TCGA pan-cancer cohorts, IGHVIII-76-1 RNA differs between tumor and matched normal tissue in 6 of 18 cancer types tested, making tumor–normal expression one of IGHVIII-76-1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where IGHVIII-76-1 RNA is repressed in tumor relative to normal tissue. In most cancer types IGHVIII-76-1 is over-expressed in tumor, although a few such as KIRC and STAD show the opposite, repressed pattern.
KIRC, STAD, and COAD are the cancer types where IGHVIII-76-1 tumor–normal differential expression is most reproducible.
