Abstract
AIM: Vascular endothelial growth factor (VEGF) is an angiogenic factor whose production is increased in pre-eclampsia (PE). Therefore, the present study was conducted aiming at assessing the possible association of VEGF polymorphisms with PE susceptibility in the southeast of Iran. MATERIAL AND METHODS: Overall, 192 PE women and 186 unrelated age-matched normotensive pregnant women were genotyped for the VEGF-2578C/A (rs699947), -1154G/A (rs1570360), and -634G/C (rs2010963) polymorphisms using the polymerase chain reaction-restriction fragment length polymorphism method. Serum VEGF levels were determined by the enzyme-linked immunosorbent assay method. RESULTS: There was no significant difference in VEGF-2578C/A, -1154G/A and -634G/C polymorphisms between PE women and controls. However, the frequency of VEGF-634GC and CC genotypes was significantly higher in women with severe PE compared to mild PE and controls. In addition, serum VEGF levels were significantly lower in PE women. The VEGF-634CC genotype was associated with lower serum VEGF levels compared to the VEGF-634GG genotype. Moreover, serum VEGF levels were significantly lower in individuals with the VEGF-634CC genotype compared to VEGF-634GC genotype only in the control group. The mean serum VEGF levels did not differ significantly between genotypes of VEGF-2587C/A and -1154G/A polymorphisms. CONCLUSION: Our findings suggest that the association of VEGF-634G/C polymorphisms with severe PE and the VEGF-634CC genotype was correlated with lower serum VEGF levels.
