Various abnormal laboratory data could be interpreted as follows: renal function impairment (creatinine 1.2 (0.9–2.4) mg/dL), hyponatremia (sodium 135 (131–139) mg/dL), hyperbilirubinemia (bilirubin 4.1 (1.9–9.8) mg/dL), hypoalbuminemia (albumin 2.4 (2.2–2.8) g/dL), the prolonged international normalized ratio for the prothrombin time (INR 1.6 (1.4–2.2)), anemia (Hb 9.6 (8.4–11.0) g/dL), and thrombocytopenia (PLT 74.0 (48.0–122.0) × 1000/μL). The gene discussed is GSTM1; the disease is anemia.
