    Abstract:
    OBJECTIVE: To investigate the distributions of genotypic and allelic frequencies of intercellular adhesion molecule-1 (ICAM-1) gene K469E and platelet endothelial cell adhesion molecule-1 (PECAM-1) gene C373G in patients with preeclampsia. METHODS: Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and DNA sequencing were used for detecting ICAM-1 gene K469E and PECAM-1 gene C373G genotypes in 110 women with preeclampsia and 110 normotensive pregnant women in comparison with their clinical characteristics. ESULTS: The distributions of observed and expected genotype frequencies were consistent with Hardy-Weinberg equilibrium. No significant differences were found in the genotype and allele frequencies of ICAM-1 gene K469E between the two groups (P>0.05), but the CC and the CG genotype frequencies of PECAM-1 gene C373G were significantly different between them (P<0.05). The relative risk for preeclampsia of CG genotype was 1.959 folds of that in CC genotype carriers (OR=1.959, 95%CI: 1.090-3.520, P=0.024), and this association still existed after adjustment for age, gravidity, parity and BMI in logistic regression models. The C373G allele frequencies showed no significant difference between the two groups (P>0.05). CONCLUSIONS: The CG genotype of PECAM-1 gene C373G genetically predispose the carriers to preeclampsia, while ICAM-1gene K469E polymorphisms is not associated with preeclampsia.
