Abstract

Introduction: Gliomas is one of the most frequent types of primary malignant tumors in the central nervous system (CNS), accounting for 75% of all primary malignant brain tumors. The alterations in the TERT promoter have been reported in 70% to 80% of gliomas, suggesting a pivotal role in oncogenesis. The identification of TERT mutations is essential and is currently integrated into gliomas diagnostic procedures. Objective: To study the ASO-SYBR Green PCR procedure for detecting the c.-146C>T mutation in DNA obtained from patients with gliomas. Methods: A cross-sectional descriptive study. Designing specific primers and optimizing the ASO-PCR conditions to detect c.-146C>T mutation. The procedure were validated by the Sanger sequencing. Results: Successully designed primers and optimized the ASO- SYBR Green PCR procedure to detect c.-146C>T mutation. The c.-146C>T mutation results showed 100% concordance with Sanger sequencing results. Conclusion: The successful optimization of the c.-146C>T mutation detection approach by ASO- SYBR Green PCR.
