This confirmed that gliomas with 1p19q codeletion overexpressed neuronal/normal brain genes (AKR1C3, C20orf42, CTTNBP2, L1CAM, GALNT13) as well as genes implicated in gliogenesis and neurogenesis (OLIG2, BMP2, NOG, DCX, ATOH8). This evidence concerns the gene L1CAM and central nervous system cancer.
