For PRDM16 focal CNAs were detected in 2 out of 12 GBM samples, while the region around the MSH5 gene was amplified in 3 out of 6 DA samples, in 7 out of 12 GBM samples, but also in 4 out of 11 PA samples (among the PA samples there was also one deletion). This evidence concerns the gene PRDM16 and glioblastoma.
