Figure 5From: Deep sequencing of multiple regions of glial tumors reveals spatial heterogeneity for mutations in clinically relevant genesHeterogeneity of PDGFRA amplification in BI06. (A) Copy number estimates based on smMIP probe data. PDGFRA amplification (labeled) occurs in region A with only mild amplification in region B and no clear detectable amplification in regions C, D or E. (B) Results from Taqman qPCR targeting PDGFRA performed in quadruplicate. Region X refers to a region of brain tissue grossly uninvolved by tumor. PDGFRA amplification occurs in region A (approximately four-fold amplification) with only mild amplification in regions B, C, D and E. Error bars represent the mean +/- one standard deviation from quadruplicate values.Back to article page
