Compared with the healthy control group, CHC patients had significantly higher aspartate transaminase (AST, p < 0.0001), alanine aminotransferase (ALT, p < 0.0001), gamma-glutamyl transferase (γGT, p < 0.0001), and fasting plasma glucose (p < 0.0001) levels. The gene discussed is GPT; the disease is cryohydrocytosis.
