Across TCGA pan-cancer cohorts, DSCAM-IT1 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of DSCAM-IT1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where DSCAM-IT1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types DSCAM-IT1 is over-expressed in tumor.
KIRC are the cancer types where DSCAM-IT1 tumor–normal differential expression is most reproducible.
