Human interleukin-5 (IL-5) is a selective eosinophilopoietic and
eosinophil-activating growth hormone. By in situ hybridization this gene is
mapped to chromosome 5q23.3 to 5q32. It is shown to be deleted in two
patients with the 5q-syndrome and in one patient previously diagnosed with
myelodysplasia whose condition had progressed to acute myeloblastic
leukemia. The clustering of other genes involved in hematopoiesis (IL-3,
granulocyte-macrophage colony-stimulating factor, feline sarcoma viral
oncogene homolog, colony-stimulating factor 1) to the same region as IL-5
suggests a nonrandom localization and raises interesting questions
concerning the evolution and regulation of these genes.
