Abstract:
Glioblastoma multiforme (GBM) is the most common and lethaltype of brain cancer. To identify the genetic alterations inGBMs, we sequenced 20,661 protein coding genes, determined thepresence of amplifications and deletions using high-densityoligonucleotide arrays, and performed gene expression analysesusing next-generation sequencing technologies in 22 human tumorsamples. This comprehensive analysis led to the discovery ofa variety of genes that were not known to be altered in GBMs.Most notably, we found recurrent mutations in the active siteof isocitrate dehydrogenase 1 (IDH1) in 12% of GBM patients.Mutations in IDH1 occurred in a large fraction of young patientsand in most patients with secondary GBMs and were associatedwith an increase in overall survival. These studies demonstratethe value of unbiased genomic analyses in the characterizationof human brain cancer and identify a potentially useful geneticalteration for the classification and targeted therapy of GBMs.
