The occurrences of copy number variations (CNVs) and somatic mutations of 31 prognostic genes are summarized in Figure 1C. Within the dataset of 173 tumor samples, the waterfall plot in Figure S1A reveals that these 31 prognostic genes underwent mutations at a frequency of 4.05%, with P4HA1 displaying the highest mutation rate. This evidence concerns the gene P4HA1 and neoplasm.
