Laboratory tests revealed hypokalemia (3.2 mmol/L), elevated C-reactive protein (CRP) (320 mg/L), acute kidney injury (creatinine 115 μmol/L, baseline 85 μmol/L), anemia (hemoglobin 112 g/L), lymphopenia (0.5 × 109 cells/L), and neutropenia (1.5 × 109 cells/L) with a normal leukocyte count (4.6 × 109 cells/L). The gene discussed is CRP; the disease is lymphopenia.
