Studies on the frequencies of PGM1, PGM3 and Es-D types from hair roots in Japanese subjects and the determination of these types from old hair roots.

The frequencies in Japanese subjects are reported of hair roots type PGM1, PGM3, and Es-D, and the determination of these types from old hair roots. The gene frequencies were: PGM11, 0.762; PGM21, 0.230; PGM 71, 0.008; PGM13, 0.621; PGM23, 0.379; Es-D1, 0.625; and Es-D2, 0.375. The old hair roots were analysed after storage at 25 degrees C, 4 degrees C and -80 degrees C; the enzyme activities were detected and typed at 25 degrees C within PGM1 10 days, PGM3 4 days, and Es-D 4 days.
