Here, subtype‐specific events involving either DNA copy number loss or CpG promoter methylation were found to involve TENC1, RARA, PCDHB11, PCDHB14, PCDHGA2 and PCDHGB2 indicative of candidate tumor suppressor genes in this context (Figure 5B; Supplementary Figure 3). Here, PCDHB14 is linked to neoplasm.
