| Abstract: | The distribution of gene frequencies in the phosphoglucomutase-1 (PGM1) system was investigated in two Japanese populations from Yamaguchi (Western Japan) and Okinawa (Southern Japan) using an improved isoelectric focusing method permitting the successful detection of the most anodal variant PGM1 3+. PGM1*7+ occurred with a polymorphic frequency of 0.012-0.021. A difference in the gene frequency was observed between the two populations. In comparison with neighboring populations, the Yamaguchi population was similar to Mongolians and Koreans in North China, and Okinawa to Zhuang in South China. |
