NAMPT and glioblastoma: Similarly, two SNVs (chr7:105984983A>T and chr7:105985025G>A) were detected within EE-019 (EE-019A and EE-019B), a gene regulatory element which potentially interacts with the GBM-related genes nicotinamide phosphoribosyltransferase (NAMPT) and high mobility group box protein 1 (HBP1) (Fig. 1D).
