Assignment of phosphoglycerate mutase (PGAMA) to human chromosome 10. Regional mapping of GOT1 and PGAMA to subbands 10q26.1 (or q25.3).

Human phosphoglycerate mutase (PGAM, EC 2.7.5.3) is under the control of two structural loci that code for subunits A and B. By means of gene-dosage studies, Bücher et al. (1980) have assigned the loci for GOT1 and PGAMA to chromosome 19 of Mus musculus. Because of the known homologies between human and murine chromosomes, gene dosage studies were carried out in erythrocytes from one patient trisomic for the entire band 10q26 and from another patient monosomic for 10q26.2 and q26.3. Results were compatible with the assignment of PGAMA and GOT1 to 10q26.1 (or 10q25.3).
