Table 4.
The frequency of the alleles of the −725 C>G polymorphism in the HLA-G promoter region shared by both parents in the pairs with pregnancies complicated by antiphospholipid syndrome (APS), preeclampsia (PE), intrauterine growth restriction (IUGR), recurrent spontaneous abortion (RSA), and the control group. Results are from chi-square tests.
