Comparision of the genomic characteristics between ERG-positive and ERG-negative groups. (a) The number of gene fusions in the two groups. Fusions present in more than two patients are shown. Red stars: fusions with significantly different frequency (p < 0.05, fisher test). (b) The frequency of significantly mutated genes in the two groups. Genes with significantly different mutation frequency in the two groups are marked with red stars. (p < 0.01, chi-squared test). The frequency of copy number amplification (c) and deletion (d) in two groups. Significantly altered cytobands separately detected in each group are annotated in black. Recurrently altered cytobands with significantly different frequency between the two groups are indicated in red. (chi-squared test, p < 0.01; frequency > 30%). Common (e) and group-specific (f) SCNA genes.
