Background: The vascular endothelial growth factor (VEGF) has a critical role in vasculogenesis and vascular permeability in several diseases including preeclampsia. There are at least 30 single nucleotide polymorphic (SNP) places on this gene. VEGF G+405C, C-2578A and C-460T SNPs are known to be related to VEGF production. VEGF polymorphisms were studied in preeclampsia, but not in HELLP syndrome. Therefore, we decided to determine the allele and genotype frequencies of VEGF G+405C, C-460T and C-2578A SNPs in healthy pregnant women and HELLP syndrome patients.
