Across TCGA pan-cancer cohorts, FEM1AP3 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of FEM1AP3’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where FEM1AP3 RNA is repressed in tumor relative to normal tissue. In most cancer types FEM1AP3 is over-expressed in tumor, although a few such as KIRP and KIRC show the opposite, repressed pattern.
KIRP, KIRC, and THCA are the cancer types where FEM1AP3 tumor–normal differential expression is most reproducible.
