Analysis of human-Chinese hamster somatic cell hybrids with spontaneously derived chromosome structural changes has provided data for the regional and subregional localization of gene loci which have previously been assigned to human chromosomes 2, 12, and X. Correlation of the expression of human gene loci with the human chromosome complements present in somatic cell hybrids indicates that the cytoplasmic malate dehydrogenase (MDH1) locus is in the 2p23yields2pter region, and red cell acid phosphatase (AcP1) is at or adjacent to 2p23. The cytoplasmic isocitrate dehydrogenase (IDH1) locus is at or adjacent to 2q11, peptidase B (Pep B) is at or adjacent to 12q21, lactate dehydrogenase B (LDH B) is in the 12q21yiedls12pter region, glucose-6-phosphate dehydrogenase (G6PD) is in the Xq24yieldsXqter region, and the gene loci for phosphoglycerate kinase (PGK), alpha-galactosidase (alpha-gal), and hypoxanthine guanine phosphoribosyltransferase (GPRT) are in the Xp21yieldsXq24 region.
