To identify PKCθ mutations in human cancers, we utilized several online databases including the cBioPortal for Cancer Genomics [48–50], The Cancer Genome Atlas (TCGA), the Dependency Map (DepMap) Portal [51–56], the Catalogue of Somatic Mutations in Cancer (COSMIC) [57], and the Mitelman Database of Chromosome Aberrations and Gene Fusions in Cancer [58,59]. This evidence concerns the gene PRRT2 and cancer.
