The aim of this study was to investigate the possible role of multiple inherited thrombophilic gene variations in women with unexplained spontaneous abortions. For this purpose, the Factor V Leiden (FVL) (rs6025), Prothrombin G20210A (rs1799963), MTHFR C677T (rs1801133), PAI-1 4G/5G (rs1799889), ACE I/D (rs1799752), eNOS E298D (rs1799983), and Apo E E2/E3/E4 (rs429358) polymorphisms were genotyped and correlated in spontaneously aborted fetal materials, their mothers and fertile women. Twenty three abortion materials, 22 women with ≥1 unexplained fetal loss, and 22 control subjects with at least two healthy term infants as a control group were studied. Target SNPs for each gene were analyzed by real time-PCR technique after genomic DNA isolation from maternal blood-EDTA, control group blood-EDTA and spontaneously aborted fetal tissues. Some cases had a single thrombophilic polymorphism, but the rest of the patients and fetal materials had combined thrombophilic polymorphisms. The PAI-1 4G/5G+4G/4G (P= 0.0017), 4G/4G (P= 0.0253), eNOS 894GT+894TT (P=0.0011) genotypes and T allele (P=0.0185), Apo E E3/E4+E3/E2+E2/E4 (P<0.0001) genotypes, E2 (P<0.0001) and E4 (P<0.0001) alleles were higher in spontaneously aborted fetal materials when compared to their mothers and control group. The Factor V Leiden rs6025, Prothrombin G20210A, MTHFR C677T, ACE I/D genotypes were different for each group but not statistically significant due to relatively small size of the samples (P>0.05). Our results indicated that combined thrombophilic gene variations may be associated with increased risk for spontaneous abortions and results need to be confirmed by larger sample size.

Background VEGF gene has been reported to be related with many diseases and recurrent pregnancy loss in various studies. VEGF polymorphisms are risk factors for pregnancy losses، and generally studies report only women’s genetic analyses. To evaluate the association between VEGF A C405G، C460T، C936T and C2578A polymorphisms and spontaneous abortion، we studied the genotypes of spontaneously aborted fetuses، their mothers and healthy control cases. Methods 23 spontaneously aborted fetal materials، 22 mothers who had these abortions and 86 healthy control cases included to this study. VEGF A C405G، C460T، C936T and C2578A polymorphisms are analysed by Real Time PCR technique after genomic DNA isolation from all samples. Results VEGF A +405GG genotype and +405G allele were higher in fetuses comparing both with mothers and healthy control group. VEGF A +936TT genotype and +936T allele were higher in fetuses comparing with mothers. VEGF A +460C/T polymorphism CT and TT genotypes were higher in fetuses comparing with mothers. Conclusions We ascertained that VEGF A +405C/G، +460C/T، and +936C/T polymorphisms are risk factors for spontaneous abortion in fetal genotypes comparing with their mothers and healthy control cases.
