[The preliminary study on the gene mutations of sixty patients with G6PD deficiency in Yunnan province].

OBJECTIVE

To analyze the types and distribution of glucose-6-phosphate dehydrogenase (G6PD) gene mutations in Yunnan province.

METHODS

By using the natural primers or mis-matched primers mediated polymerase chain reaction (PCR) followed by endonuclease digestion methods, six types of G6PD gene mutations, G1388A, G1376T, C1024T, G392T, C592T and A95G were in sixty patients with G6PD deficiency.

RESULT: Six types of mutation were revealed: 28.3% (17 of 60) were G1388A, 11.7% (7 of 60) G1376T, 6.7% (4 of 60) C1024T, 1.7% (1 of 60) G392T, 1.7% (1 of 60) C592T, 1.7% (1 of 60) A95G and 48.3% (29 of 60) unidentified. C592T mutation is the first report in Yunnan people.

CONCLUSIONS

The G6PD gene in Yunnan people is heterogeneous. Research of G6PD gene mutation types may provide some useful data for clinical diagnosis and prevention of G6PD deficiency, and for human genetic study.
