Association of functional polymorphisms in FAS and FAS Ligand genes promoter with pre-eclampsia.

ABSTRACT

AIM: Pre-eclampsia (PE) is a complex disorder of pregnancy with unknown etiology. FAS-mediated apoptosis is assumed to prevent the development of PE; therefore FAS and FAS Ligand may be represented as candidate genes involved in PE pathogenesis. In the present study, we evaluated the relation between FAS Ligand A-670G (rs1800682) and FAS Ligand C-844T (rs763110) gene polymorphisms with PE in southeast Iran. METHODS: One hundred and twenty-seven unrelated women with PE and 139 healthy control subjects were genotyped for the FAS A-670G and FAS Ligand C-844T polymorphisms by polymerase chain reaction restriction fragment length polymorphism method. RESULTS: The AA, AG and GG genotype frequency of the FAS A-670G polymorphism were 21.3%, 53.5% and 25.2% in pre-eclamptic women and 46.0%, 41.5% and 11.5% in controls and were statistically different (P = 0.0001). The risk of PE was 2.7- and 4.7-fold higher in pregnant women with AG and GG genotypes respectively. Although the frequency TT genotype and T allele of FAS Ligand C-844T gene polymorphism was higher in the PE group, the differences were not significant. CONCLUSION: FAS A-670G polymorphism is associated with a higher risk for PE. There was no association between FAS Ligand C-844T polymorphism and PE.
