NBDC Research ID: hum0006.v4

SUMMARY

Aims: The identification of genomic/genetic alterations in brain tumors (gliomas) and analysis of their clinicopathological significance.

Methods: Exome sequencing, RNA sequencing and Methylation array were performed. Matched normal DNA was also used for Exome sequencing.

Participants/Materials:

Surgical specimen obtained from 6 patients with astrocytoma (primary and matched recurrent samples) and paired normal peripheral blood cells (total: 23 samples).

Surgical specimen obtained from 16 patients with oligodendroglioma (12 primary and matched recurrent samples, 8 samples obtained from 4 patients by multi-sampling)

Surgical specimen obtained from patients with gliomas (17 patients with diffuse cerebellar glioma, 8 patients with cerebral glioblastoma and 14 patients with thalamic glioma)

Surgical specimen obtained from 94 patients with gliomas, including primary and matched recurrent samples (total 114 samples) and paired normal blood cells
