Across TCGA pan-cancer cohorts, FAM74A1 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of FAM74A1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where FAM74A1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types FAM74A1 is over-expressed in tumor.
KICH are the cancer types where FAM74A1 tumor–normal differential expression is most reproducible.
