To investigate the association between the polymorphism of HLA-A, HLA-B genes and pre-eclampsia.HLA-A, HLA-B genotyping was performed by polymerase chain reaction sequence-specific primer (PCR-SSP) in 119 preeclampsia patients, 117 normal pregnant women and their neonates.The study showed that 16 HLA-A and 39 HLA-B alleles were obtained in pre-eclamptic patients and normal pregnant women. 15 HLA-A and 37 HLA-B alleles were obtained in their neonates. No significant difference was found in maternal or neonatal HLA-A, HLA-B alleles between pre-eclampsia group and control group (P(c) > 0.05). The frequencies of HLA-A11, HLA-A24, HLA-B13, HLA-B14, HLA-B15, HLA-B52 maternal/fetus genetic associations were significantly different between pre-eclampsia group and control group (P < 0.05).Some HLA-A,HLA-B maternal/fetus special bindings may be associated with the susceptibility or protective of pre-eclampsia.
