Background: Development of different molecular markers has given a new insight in the glioma
management. KIAA1549-BRAF gene fusion has a diagnostic and prognostic significance.
Aim: The aim of this study was to determine the KIAA1549-BRAF gene fusion in glioma and their
correlation with various clinical parameters.
Material and Methods: Forty cases of glioma were studied for KIAA1549-BRAF gene fusion by reverse
transcription-PCR (RT-PCR).
Results: Overall, KIAA1549-BRAF gene fusion was found in 22% (9/40) cases of glioma. Children had
higher KIAA1549-BRAF fusion (72%; 8/11) as compared to adults (10%; 3/29) and this difference was
statistically significant. Cerebellar location of tumor was significantly associated with KIAA1549-BRAF
fusion. KIAA1549-BRAF fusion was highest in pilocytic astrocytoma (89%), and this difference was
statistically significant. Statistically significant difference was noted between KIAA1549-BRAF fusion
expression and WHO grade I glioma.
Conclusion: Overall, KIAA1549-BRAF gene fusion was found in 22% (9/40) cases of glioma. Childhood
age, pilocytic astrocytoma histology, cerebellar location and WHO grade I tumor were significantly
associated with KIAA1549-BRAF gene fusion.
