There were few tumour phenotypic differences between receptor-positive and negative vessels, save for an increased proportion of oligodendroglial-predominant glioblastoma specimens with KIT positive endothelial cells (25/69, 36.2% vs 33/177, 18.6%, p = 0.0022, Fishers exact test) (Figure 5B). The gene discussed is KIT; the disease is glioblastoma.
