Across TCGA pan-cancer cohorts, MYOD1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of MYOD1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where MYOD1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MYOD1 is over-expressed in tumor.
KIRC, UCEC, and LUSC are the cancer types where MYOD1 tumor–normal differential expression is most reproducible.
