[Frequencies distribution of GSTT1 and GSTM1 null genotypes in 24 Yunnan populations].
OBJECTIVE
To investigate the frequencies distribution of GSTT1 and GSTM1 null genotypes in 24 Yunnan populations.


METHODS
GSTT1 and GSTM1 genotypes were analyzed by PCR procedure.


RESULTS
The range of frequencies for GSTT1 and GSTM1 null genotypes in the populations were 0.188-0.633 and 0.400-0.745, respectively, and in the districts were 0.286-0.583, 0.433-0.745 respectively. There was significant relationship between GSTT1 frequencies and populations.


CONCLUSIONS
The frequencies of GSTT1 and GSTM1 null genotypes in 24 Yunnan populations were different, but they were almost the same in different districts of Yunnan.
