Across TCGA pan-cancer cohorts, IGLVI-20 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of IGLVI-20’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where IGLVI-20 RNA is repressed in tumor relative to normal tissue. In most cancer types IGLVI-20 is over-expressed in tumor, although a few such as COAD and STAD show the opposite, repressed pattern.
COAD, LUAD, and STAD are the cancer types where IGLVI-20 tumor–normal differential expression is most reproducible.
