Laboratory examination revealed slightly elevated liver enzyme level (aspartate transaminase, 46 IU/mL; alanine transaminase, 20 IU/mL; reference range 0–40), hyperbilirubinemia (total bilirubin concentration, 1.6 mg/dL; reference range 0.2–1.2), thrombocytopenia (platelet count of 93 × 103/μL), and prolonged prothrombin time (1.46 international normalized ratio, reference range 0.8–1.2), suggesting liver dysfunction. This evidence concerns the gene F2 and Hyperbilirubinemia.
