found that relative telomere length and RTEL1 mRNA correlated with predicted worse progression in glioma patients, but not in meningioma patients (P < 0.01), and that increased relative telomere length was weakly correlated with RTEL1 mRNA expression (R2 = 0.248, P < 0.001) [64]. The gene discussed is RTEL1; the disease is central nervous system cancer.
