We interrogated the Ivy Glioblastoma Atlas Project (Ivy GAP) database, which contains data from 55 glioblastomas regionally microdissected with RNA sequencing (http://glioblastoma.alleninstitute.org/), and investigated the relationship between the expression of ZDHHC18 and ZDHHC23 and their anatomical distribution. The gene discussed is ZDHHC23; the disease is glioblastoma.
