Abedalthagafi et al. presented a case of a patient with intraventricular meningioma with morphological heterogeneity and found that TERT mRNA expression was low in grade I area of the meningioma but identified the same TPM (C228T) in both the grade II and III sections leading to increased TERT expression in high-grade areas [89]. Here, TERT is linked to meningioma.
