Across TCGA pan-cancer cohorts, SNORA1B RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of SNORA1B’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where SNORA1B RNA is repressed in tumor relative to normal tissue. In most cancer types SNORA1B is over-expressed in tumor, although a few such as KICH and LUSC show the opposite, repressed pattern.
KICH, LUSC, and COAD are the cancer types where SNORA1B tumor–normal differential expression is most reproducible.
