Five types of glycophorin variants found in southern China.
OBJECTIVE
To summarize the results of gene analysis for five types of glycophorin (GP) variants found in a screening survey conducted in several regions of Southern China.


METHODS
Papers cited in Chinese biochemical and biomedical literatures with a bibliographic review of articles relevant to hematology and biochemistry.


METHODS
All GP variant reports of our research group published during 1991-1997 were included.


METHODS
Data concerning 5 types of GP variants found in Southern China were briefly abstracted. GP variant frequencies with their phenotypes among 3 districts and those among Han, Li, Buyi and Yao ethnic groups were calculated.


RESULTS
Five phenotypes of GP variants [Sta, Mi III, Mi V (J.L.), Mi VI and a novel case] were identified from 180 unrelated healthy individuals (Hunan, Hainan) and 222 residents of a tertian malaria hyperendemic area (Guizhou), using immunoblotting techniques, Southen hybridization and PCR-direct sequencing.


CONCLUSIONS
These five types of GP variants were first reported in China. There were some differences in the geographical distribution of GP variants among Hunan, Hainan and Guizhou districts. Mi III GP was commonly found in national minorities of Li and Buyi, while the frequency of Sta GP occurrence was considerably higher in Han ethnic group. The frequency of GP variants in a malaria hyperendemic area of Guizhou Province does not depend upon the severity of tertian malaria morbidity.
