Isoelectric focusing studies of human red cell PGM1 in Japanese, with special reference to the characterization of PGM17.
The distribution of phosphoglucomutase (PGM1) subtypes in human red cells was determined by isoelectric focusing in 218 Japanese samples. Nine common phenotypes were observed corresponding to the following frequencies of the four alleles at the PGM1 locus: PGM11+ 0.6560, PGM11- 0.1170, PGM12+ 0.1674 and PGM12- 0.0505. In addition, a characterization of the PGM17 allele was performed. Our results obtained in the present study revealed the possibility that the PGM17 allele may be differentiated in the two alleles of PGM17+ and PGM17- through an investigation of isoelectric focusing.
