We first confirmed the mRNA expression of the CCAN (CENP-A, CENP-C, CENP-T), KMN (KNL1, Mis12, Ndc80), and RZZ (ROD, Zwilch, ZW10) complexes, as well as Zwint-1, in clinical PC specimens from TCGA (n = 179) and normal tissues from GTEx data (n = 171) using the publicly available GEPIA database. This evidence concerns the gene CENPT and pachyonychia congenita.
