Landscape of genetic variation of necroptosis-related genes in colorectal cancer. A A flowchart of our study. B Gene ontology annotation of necroptosis-related genes. C Oncoplot show genetic alterations of 33 NRGs in CRC. The number on the right indicated the mutation frequency in each gene. Each column represented individual patients. D CNV frequency of 33 NRGs in CRC tumors. E Locations of CNV alterations in NRGs on 23 chromosomes. F Principal component analysis of necroptosis-related genes to distinguish tumors from normal samples in TCGA-COAD/READ cohort. All samples: n = 626; tumor: n = 578; normal: n = 48. G Expression distributions of 33 NRGs between normal and CRC tissues
