Mild thrombocytopenia and abnormal coagulation tests (notable lower prothrombin levels) were found, along with increased liver enzyme levels, hyperbilirubinemia (total bilirubin 4 times the ULN), and a serology consistent with an acute HEV and chronic HBV infection (positive HBsAg, HBeAb, IgG HBc Ab, IgM HEVAb, HBV viral load 20,000,000 IU/mL). The gene discussed is F2; the disease is Hyperbilirubinemia.
