title: Somatic cell hybrid mapping of human chromosome band 5q31: a region important to hematopoiesis.
abstract: As a means of characterizing the distal long arm of chromosome 5, in particular, the region spanning 5q23-->q31, we analyzed somatic cell hybrids prepared from cells with overlapping chromosomal rearrangements. In one hybrid, the derivative chromosome 5 from a patient with acute myeloid leukemia (AML) de novo, whose bone marrow cells had a balanced translocation, t(5;7)(q31;q22), involving chromosome band 5q31, was isolated in a somatic cell hybrid (B294). In addition, we prepared somatic cell hybrids from a lymphoblastoid cell line (CC) derived from a patient who has a constitutional interstitial deletion of chromosome 5 spanning 5q23.1-->q31.1. By a combination of Southern hybridization analysis and fluorescent in situ hybridization, we constructed a map dividing 5q23-->q31 into four regions. We can assign genes to these regions and relate them to anonymous RFLP markers that have been genetically mapped.
