The above studies identified that NCAPG2 was significantly over-expressed in PC and that survival analysis demonstrated that NCAPG2 expression levels were strongly correlated with OS (p=0.01), DSS (p=7.8e-3), PFS (p=0.01), and DFS (p=0.02) in PC patients. The gene discussed is NCAPG2; the disease is pachyonychia congenita.
