Across TCGA pan-cancer cohorts, IGKV2D-10 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of IGKV2D-10’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where IGKV2D-10 RNA is repressed in tumor relative to normal tissue. In most cancer types IGKV2D-10 is over-expressed in tumor, although a few such as BRCA and LIHC show the opposite, repressed pattern.
BRCA, LIHC, and LUSC are the cancer types where IGKV2D-10 tumor–normal differential expression is most reproducible.
