Laboratory investigations revealed leukocytosis (white blood cell count: 10.96 × 109/L, normal reference range: 3.5–9.5 × 109/L), neutrophilia (neutrophil count: 9.24 × 109/L, normal reference range: 1.8–6.3 × 109/L), and a significantly elevated high-sensitivity C-reactive protein (hs-CRP) level (119.13 mg/L, normal reference range: 0–6 mg/L). The gene discussed is CRP; the disease is Increased total leukocyte count.
