Abstract
Red cell phosphoglucomutase phenotypes were studied in 201 Japanese donors.
Table 5. Distribution of PGM types in relation to acid phosphatase type.
*No. observed (No. expected) x2=1.89 4d.f. P>0.75.
Gene frequencies were PGM1=0.786 add PGM2=0.214.
Phosphoglucomutase types were concordant in all of 20 pairs of monozygotic twins. Of thiteen pairs of dizygotic twins, eight were concordant and five pairs were discordant.
No association between phosphoglucomutase types and the ABO blood groups or red cell acid phosphatase types were observed.
This work was partly aided by the fund of the Ministry of Education.
The authors are indebted to Dr. K. WATANABE, Chiba Red Cross Blood Center and Dr. K. YAMASAWA, Department of Legal Medicine, University of Tokyo, for their providing the samples of blood donors, and twin materials.
