Maternal and fetal HLA-G 14 bp gene polymorphism in pregnancy-induced hypertension, preeclampsia, intrauterine growth restricted and normal pregnancies

Abstract

With this study we filled several gaps occurring in previous studies: we analyzed a very well-defined population of PE, PIH and IUGR pregnancies, considering both fetal and maternal HLA-G 14 bp polymorphism, individually and jointly. Our findings showed that fetal and maternal HLA-G 14 bp genotypes are not associated with increased risk for the development of obstetrical complications, suggesting that this polymorphism has no immuno-modulatory role in the development of PE, PIH or IUGR.
