They were: aristaless related homeobox (ARX), chemokine (C-X-C motif) ligand 14 (CXCL14), G protein-coupled receptor 17 (GPR17), LIM homeobox 2 (LHX2) and prostaglandin D2 synthase (PTGD2S), whose expressions resulted down-regulated in infratentorial tumours and up-regulated in supratentorial ones. Here, LHX2 is linked to neoplasm.
