    Abstract:
    OBJECTIVE: To investigate whether vascular endothelial growth factor (VEGF) gene 5'-UTR-460 polymorphism could be used as a marker of susceptibility to endometriosis. STUDY DESIGN: Women were divided into 2 groups, endometriosis (n = 122) and nonendometriosis (n = 131). Polymorphisms for VEGF were detected by polymerase chain reaction and BstUI (New England Biolabs, Beverly, Massachusetts) restriction enzyme analysis. Genotypes and allelic frequencies between the groups were compared. RESULTS: Proportions of different VEGF polymorphisms in the groups were significantly different. Proportions of cuttable (C) homozygote/heterozygote/ uncuttable (T) homozygotefor VEGF in the groups were 0/44.3/55.7% and 0/63.4/36.6%, respectively. A higher percentage of T/F homozygote and T allele was present in the endometriosis population. The proportions of C/T alleles in the groups were 22.1/77.9% and 31.7/68.3%, respectively. CONCLUSION: T/T homozygotes and the T allele of the VEGF-460 gene are associated with a higher risk of endometriosis. Heterozygotes and C allele are related to the lower risk of endometriosis formation. VEGF polymorphism likely contributes to the pathogenesis of endometriosis and may become a useful markerfor predicting endometriosis susceptibility.
