1. ABSTRACT

The present study was designed to explore the association between the SNP +405G>C of the VEGF gene with the risk of endometriosis, and endometriosis associated with adenomyosis and chocolate cysts. Following extraction of genomic DNA, genotyping of the +405 G>C polymorphisms of the VEGF gene was performed by PCR - RFLP analysis. The genotype (X2 =21.713, 2 df, P = < 0.0001) and allele (X2 =10.697, 1 df, P = 0.0011) frequencies of endometriosis patients were significantly different from those of the control women. The genotype and allele frequencies significantly differed in all the clinical subgroups of endometriosis patients. The significant differences in allele frequencies were the result of an increased proportion of homozygote GG genotype carriers. No significant difference was observed between the clinical subgroups with respect to the genotype and allele frequencies of the VEGF +405G>C polymorphism. These findings suggest that the VEGF +405 G>C polymorphism is associated with the risk of endometriosis, and endometriosis associated with adenomyosis and chocolate cysts.
