ABSTRACT
Objective:To explore the mechanism of association between recurrent spontaneous abortion(RSA) and the polymorphism of HLA E,had detected the frequencies of five HLA E alleles in 53 women with RSA and 156 random Shanghai Chinese controls.Methods:PCR sequence specific oligonucleotide (PCR SSO) typing was carried to detect polymorphism in exon2 and exon3 of HLA E gene.Results:HLA E *0101 is the most common allele in both RSA patients and controls(50% and 43.09% respectively).HLA E *01031 and E *01032 were detected with allele freqencies of 23.79% and 33.12% in controls,20.75% and 29.25% in RSA.No HLA E *0102 and E *0104 alleles could be detected in both groups.Conclusion:Maternal HLA E polymorphism does not associated with pathogenesis of RSA.
