Across TCGA pan-cancer cohorts, SAMD11P1 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of SAMD11P1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where SAMD11P1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types SAMD11P1 is over-expressed in tumor, although a few such as KICH and THCA show the opposite, repressed pattern.
KIRC, KICH, and BRCA are the cancer types where SAMD11P1 tumor–normal differential expression is most reproducible.
