Notably, serum GP73 correlated with inflammatory activity grade (rho = 0.655, P < 0.001; rho = 0.547, P < 0.001), platelet count (rho = −0.422, P < 0.001; rho = −0.486, P < 0.001), and direct bilirubin (rho = 0.562, P < 0.001; rho = 0.480, P < 0.001) in patients with AIH or PBC. The gene discussed is GOLM1; the disease is primary biliary cholangitis.
