Laboratory tests indicated hyperkalemia (potassium of 5.9 mmol/L), raised liver enzymes (aspartate transaminase of 282 IU/L and alanine transaminase of 273 IU/L), acidic blood with a significant anion gap, raised serum creatinine (3.0 mg/dl from a baseline level of 0.6 mg/dl), and high serum creatine kinase (4,000 U/L) and troponin I (0.37 μ/L). The gene discussed is GPT; the disease is Hyperkalemia.
