The laboratory tests repeated after approximately 36 hours from admission showed: severe hepatic cytolysis syndrome (AST 8543 U/L, ALT 7624 U/L), elevated levels of total bilirubin (TBi 4.924 mg/dL, direct bilirubin [DBi] 4.405 mg/dL), and creatinfosfokinase 2 (1431 U/L), hypoalbuminemia (Alb 2.84 g/dL), hypoglycemia (Glu 22 mg/dL), hyponatremia [sodium (Na) 111 mmol/L], impaired renal function (creatinine 1.04 mg/dL), and altered coagulation tests [activated partial thromboplastin time (APTT) 140.6 seconds, international normalized ratio—INR unmeasurable]. The gene discussed is GPT; the disease is Hypoglycemia.
