Across TCGA pan-cancer cohorts, IGHV1OR16-4 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of IGHV1OR16-4’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where IGHV1OR16-4 RNA is repressed in tumor relative to normal tissue. In most cancer types IGHV1OR16-4 is over-expressed in tumor, although a few such as COAD and STAD show the opposite, repressed pattern.
COAD, LUAD, and KIRC are the cancer types where IGHV1OR16-4 tumor–normal differential expression is most reproducible.
