Across TCGA pan-cancer cohorts, ATP6V1G1P2 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of ATP6V1G1P2’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where ATP6V1G1P2 RNA is repressed in tumor relative to normal tissue. In most cancer types ATP6V1G1P2 is over-expressed in tumor, although a few such as KICH and COAD show the opposite, repressed pattern.
KICH, COAD, and LUSC are the cancer types where ATP6V1G1P2 tumor–normal differential expression is most reproducible.
