Mutational signatures in RCC with VTT. (A) Mutational signature analysis of the five patients. The shown signatures represent the following mutational processes: AC1 = spontaneous deamination; AC2 = APOBEC action; AC3 = homologous recombination repair defect; AC5 = unknown/metabolic stress; AC9 = Pol eta/somatic hypermutation; AC13 = APOBEC; AC17 = unknown. Note the presence of AC3 indicating defective homologous recombination repair in three of the five patients (RCC-VTT-01, -04, -05). (B) Scatterplot of exposures to signature AC3 and indel counts (2–10 bp) per sample. Wilcoxon rank-sum test between the two colour-coded groups, p ≤ 0.0001.
