Extended Data Figure 1 Mutational landscape of PC.
a, Barplot representing the somatic mutation rate for each of the 456 samples included in this analysis.b, Non-silent mutations (blue), amplifications (≥8 copies, red), deletions (purple) and structural variants (SV, green) ranked in order of exclusivity. c, Significantly mutated genes identified by OncodriverFM. An asterisk denotes a significantly mutated gene identified by both MutSigCV and OncodriverFM. d, PC mutation functional interaction (FI) sub-network identified by the ReactomeFI cytoscape plugin. Mutated genes are indicated as coloured circles and linker genes (that is, genes not significantly mutated but highly connected to mutated genes in the network) indicated as coloured diamonds. Different node colours indicate different network clusters or closely interconnected genes. P values represent FDR < 0.05. Pathways significantly enriched in the identified FI sub-network are shown in the accompanying bar graph. Linker genes were not included in the enrichment analysis. Pie chart representing significantly altered genes and pathways in PC.
Extended Data Figure 2 Selected genomic events in PC.
a, Lollipop plots showing the type and location of mutations in the RNA processing genes RBM10, SF3B1 and U2AF1 and the tumour suppressor TP53.In each plot, mutations observed across multiple cancers (top plot; PanCancer) are compared with those observed in the current study (bottom plot; PDAC). Significant recurrent mutations are labelled above the relevant lollipop. b, Regions of copy number alteration showing concordant gene expression changes. For each of the indicated chromosomes, significant GISTIC peaks are shown at their respective genomic locations (x axis) as grey bars. Each gene is represented by a dot at its specific chromosomal coordinate, with blue representing concordant copy number loss and gene downregulation and red representing concordant copy number amplification (copy number ≥ 8) and gene upregulation. Significance of concordant copy number/expression change is measured as a value of −log10 (_q_-value) times the sign of the direction of change. Dotted lines represent a significance threshold of −log10 (_q_-value = 0.05) times the sign of the direction of change. Genes showing concordant copy number/expression changes and overlapping GISTIC peaks are listed above the plot. Asterisk denotes known PC oncogenes showing amplification but non-significant concordant copy number/expression change.
