When the patient suffered the episode of bronchiolitis, the cells of the white series markedly increased, reaching total values of 15,000 leukocytes/mm3, of which 42.5% were neutrophils and 52.8% were lymphocytes, while erythrocyte, Hb, plasma protein and hormone levels remained within the normal range (except creatinine and IGF-I). The gene discussed is IGF1; the disease is bronchiolitis.
