Moreover, CNTNAP2 protein is able to interact with CNTN262, which has been linked to glioma stem cell proliferation and shows higher expression levels in oligodendrogliomas63–65, and EPB41L3 (alias DAL1, 4.1B)66, which is reported to act as a tumor suppressor gene in glioma67–69. This evidence concerns the gene CNTNAP2 and glioma.
