Across TCGA pan-cancer cohorts, FAM223B RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of FAM223B’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where FAM223B RNA is more highly expressed in tumor relative to normal tissue. In most cancer types FAM223B is over-expressed in tumor.
ESCA and BRCA are the cancer types where FAM223B tumor–normal differential expression is most reproducible.
