Recurrent episodes of neutropenia (up to 700/mm3 leukocytes and 2 neutrophils/mm3) associated with inflammatory syndrome (erythrocyte sedimentation rate = 80 mm/h, CRP = 130 mg/L) were pointed out, requiring periodic administration of granulocyte‐colony‐stimulating factor 30 MU/0.5 mL daily for 3–5 days and moderate to high doses of corticosteroids with good response (Figure 3). The gene discussed is CRP; the disease is Decreased total neutrophil count.
