Chromosome translocations and deletions may alter cellular proto-oncogenes and result in cellular changes that are important in the pathogenesis of malignancy. The region 11q23 is frequently involved in human malignancy. Utilizing a leukemic cell line with a reciprocal translocation involving 11q23 and somatic cell hybrids derived from this cell line, we analyzed five genes assigned to 11q23: NCAM, CD3D, CD3E, THY1, and ETS1. Our data showed no evidence of direct involvement of these genes in this leukemia but enabled a partial genetic map of this important region of the human genome to be constructed: 11cen—NCAM—CD3([G, D], E)—//—(ETS1, THY1)—11qter.
