Compared to the normal tissue, the expression levels of PIGC were higher regardless of the type of sample (normal, primary tumor), patient gender (male, female), patient age (20–40 years, 41–60 years, 61–80 years, and 81–100 years), patient race (Caucasian, African-American, and Asian), individual cancer stages (S1, S2, S3, and S4), and tumor grade (G1, G2, G3, G4). The gene discussed is PIGC; the disease is cancer.
