Laboratory tests revealed mild leukocytosis (white cell count at 10.40 × 109/L, reference range 3.7–10.0), mild anaemia (haemoglobin at 123 g/L, reference range 132–169), neutrophilia (neutrophils at 9.5 × 109/L, reference range 1.7–6.6), lymphocytopenia (0.5 × 109/L, reference range 1.0–3.0), mildly raised C-reactive protein (CRP) (38 mg/L, reference range < 5.0) and stable stage 4 CKD (creatinine at 185 μmol/L, reference range 53–97). The gene discussed is CRP; the disease is anemia (phenotype).
