Interestingly, several of those genes had been previously described to be overexpressed and implicated in GBM tumorigenesis, including: CA9 (carbonic anhydrase 9) (Boyd et al., 2017), PDL1 (Programmed Death Ligand 1, also known as CD274) (Jacobs et al., 2009), and IL13RA2 (Interleukin 13 Receptor Subunit Alpha 2). The gene discussed is CA9; the disease is glioblastoma.
