Study of RsaI polymorphism of the ERβ gene in Greek women with endometriosis

Abstract

Estrogens and estrogen receptors (ERs) play an important role in the pathogenesis of endometriosis. The aim of this study was to investigate the presence of gene polymorphism RsaI in the gene of the estrogen receptor ERβ in the Greek female population, and its distribution in women suffering from endometriosis and in a control group. We included 67 consecutive infertile women of Caucasian origin who were operated laparoscopically in our Gynecological Endoscopy Unit for endometriosis, and 96 women participated as control group. Patients were genotyped for RsaI (G/A, rs1256049) polymorphism in ESR2 exon 5, using real-time PCR. The patients’ genotype distribution did not differ from the control group. There were no women homozygous for the polymorphic allele in neither group. The different genotypes of ESR2 could not be associated with the stage of endometriosis. The data of this study point that in Greek population who had proven endometriosis the determination of RsaI polymorphism of ESR2 gene doesn’t offer any information for the progression of endometriosis, regarding the genetic profile of this particular gene.
