Across TCGA pan-cancer cohorts, CHRD RNA differs between tumor and matched normal tissue in 11 of 18 cancer types tested, making tumor–normal expression one of CHRD’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where CHRD RNA is repressed in tumor relative to normal tissue. In most cancer types CHRD is over-expressed in tumor, although a few such as KICH and UCEC show the opposite, repressed pattern.
KICH, UCEC, and BRCA are the cancer types where CHRD tumor–normal differential expression is most reproducible.
RNA tumor vs normal associations by lineage
Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in CHRD RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
