Chromosomal localization of human leukocyte, fibroblast, and immune interferon genes by means of in situ hybridization

Abstract
Recombinant plasmids containing cDNA inserts from human leukocyte interferon (IFN-α), fibroblast interferon (IFN-β), or immune interferon (INF-γ) genes were radiolabeled and hybridized in situ to human metaphase chromosome preparations. The results localized the human IFN-α and IFN-β genes to the short arm of chromosome 9(p21→pter) and localized the IFN-γ gene to the long arm of chromosome 12(q24.1).
