Association of specific diplotypes defined by common rs1800682 and rare rs34995925 single nucleotide polymorphisms within the STAT1 transcription binding site of the FAS gene promoter with preeclampsia.
The tolerance of fetal antigens by intradecidual T-cell involving the Fas-mediated apoptosis plays an important role in the physiological course of pregnancy. Objective of this study is to determine the association of diplotypes of common rs1800682G and rare rs34995925C alleles within the STAT1 transcription binding site of the FAS promoter region with preeclampsia. There were 116 preeclamptic women and 123 healthy control subjects from Hungary and Slovakia enrolled in the study. The presence of the GG or GA genotypes on rs1800682 was confirmed in 91 patients and 85 controls (OR = 1.628, 95%CI 0.907-2.92). The rare rs34995925 C allele laying 7 bp further from rs1800682 within STAT1 transcription binding site was detected in 3 preeclamptic cases and none healthy subjects. Haplotypes GT and AC were defined by common rs1800682G and rare rs34995925C alleles, respectively, and were considered as "low" FAS-producing. The combinations of GT or AC with normal FAS-producing haplotypes AT were considered as "low" FAS-producing diplotypes in dominant model. The "low" FAS -producing diplotype group of GT/GT, GT/AT, and AC/AT compared to the normal FAS-producing diplotype group of AT/AT showed OR = 1.91 (95%CI 1.04-3.48) and p = 0.03 for the association with preeclampsia.
