title: Genetic polymorphisms associated with thrombophilia and vascular disease in women with unexplained late intrauterine fetal death: a multicenter study.
abstract: OBJECTIVE
  We determined whether gene polymorphisms associated with thrombophilia and vascular disease as etiologic factors were involved in the pathogenesis of pregnancy-associated complications.
  
  
  METHODS
  We conducted a multicenter case-control study in which we studied 94 women with late unexplained intrauterine fetal death (IUFD) and 94 healthy women with at least one uncomplicated full-term pregnancy and no history of IUFD. We obtained blood samples from all subjects and analyzed their DNA for 12 common polymorphisms of thrombophilic and vascular genes (factor V Leiden, factor V H1299R, prothrombin G20210A, factor XIII V34L, MTHFR C677T, MTHFR A1298C, beta-fibrinogen-455 G to A, PAI-1 4G/5G, GPIIIa L33P, HFE C282Y, apolipoprotein B R3500Q, and apolipoprotein E2/E3/E4).
  
  
  RESULTS
  We found no significant association between any of the polymorphisms investigated and IUFD. Subgroup analyses involving various combinations of polymorphisms and in which gestational age and fetal weight were corrected for also showed no significant results.
  
  
  CONCLUSIONS
  Our data represent the largest study to date with respect to thrombophilic and vascular gene polymorphisms in IUFD. In accordance with others, we challenge the importance of thrombophilic and vascular gene polymorphisms in the pathogenesis of this condition.
