Aim: The aim of the present work was to evaluate associations between the risk of endometriosis and -460C/T (rs833061) and +405G/C (rs2010963) polymorphisms in the VEGF gene.
Methodology: In the present study, we examined group of 100 patients with endometriosis and 100 controls. Genomic DNA was extracted from peripheral blood. Determination of genes polymorphic variants was made using polymerase chain reaction-restriction fragment length polymorphism technique (PCR-RFLP).
Results: Presented study showed statistically significant increase in the endometriosis development risk for the -460T/T genotype (OR 3.39; 95% CI, 1.60-7.13; p = 0.002) and for the -460T allele (OR 2.49; 95% CI, 1.64-3.78; p <.0001), as well as for the +405C/C genotype (OR 2.16; 95% CI, 1.047-4.48; p = 0.035) in patients with endometriosis in comparison with healthy control group. We also observed positive association of the +405C/C genotype (OR 0.26; 95% CI, 0.08-0.79; p = 0.019) as well as the +405C allele occurrence with an increased endometriosis development risk (OR 0.31; 95% CI, 0.19-0.71; p = 0.005), assessed by the degree of rASRM classification stages.
Conclusion: The results support the hypothesis that the -460C/T and +405G/C polymorphisms of the VEGF gene may be associated with endometriosis occurrence in Poland.
