Mapping of the gene for interferon‐inducible dsRNA‐dependent protein kinase to chromosome region 2p21‐22: A site of rearrangements in myeloproliferative disorders

Abstract

Recent evidence suggests that the human interferon-inducible double-stranded RNA-dependent protein kinase may function as a tumor suppressor. Here we describe the mapping of the gene for this kinase to chromosome region 2p21-22 by fluorescence in situ hybridization. A combined analysis of cytogenetic data from a series of 341 patients with hematologic disorders that exhibited cytogenetic abnormalities and from published reports indicates that abnormalities involving 2p21-22 occur nonrandomly and are observed among patients with acute myelogenous leukemia, raising the possibility of a role for this protein kinase in leukemogenesis.
