Across TCGA pan-cancer cohorts, TAAR6 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of TAAR6’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where TAAR6 RNA is repressed in tumor relative to normal tissue. In most cancer types TAAR6 is over-expressed in tumor, although a few such as KICH show the opposite, repressed pattern.
KICH and LUAD are the cancer types where TAAR6 tumor–normal differential expression is most reproducible.
