KIAA1549:BRAF fusion gene in pediatric brain tumors of various histogenesis

Pediatr Blood Cancer. 2015 Apr;62(4):724-7. doi: 10.1002/pbc.25272. Epub 2014 Nov 8.

Abstract

The KIAA1549:BRAF fusion gene is considered a driver genetic event in pilocytic astrocytoma. We investigated a series of 69 pediatric brain neoplasms of diverse histogenesis and grade using the RT-PCR and sequencing. We detected the KIAA1549:BRAF fusion gene in five of 34 non-PA tumors (14.7%), that is, one glioblastoma, one anaplastic astrocytoma, one anaplastic pleomorphic xanthoastrocytoma, 1 ependymoma, and 1 Atypical Teratoid Rhabdoid Tumor. Our study showed that the K-B, although uncommon, it can be detected in non-PA tumors of various histogenesis and grading.
