Laboratory studies revealed normocytic anemia (hemoglobulin 4.5 mmol/l), mean corpuscular volume of 84 fL without evidence of iron-, folic acid-, or vitamin B12 deficiencies, a white blood cell count of 10.33 × 109/L, C-reactive protein level (CRP) of 54 mg/L, erythrocyte sedimentation rate of (ESR) 91 mm/hour, a serum creatinine level of 138 μmol/L, and blood urea nitrogen of 5.4 mmol/L. The gene discussed is CRP; the disease is normocytic anemia.
