Abstract Objective: To evaluate the association of intron 1 and exon 1 polymorphisms in the estrogen receptor a gene (ER-alpha) with endometriosis in women.Design: Association study.Setting: Endometriosis Unit, Federal University of São Paulo.Patient(s): the control group consisted of volunteers older than 45 years who had no evidence of endometriosis antecedents. Two groups with the disease were evaluated: the first group had stage I or 11 endometriosis and the second group stage III or IV.Intervention(s): Polymerase chain reaction (PCR) followed by digestion with HaeIII and MspI endonucleases (RFLP) were applied to detect intron I and exon I polymorphisms, respectively, in a total of 125 controls and 105 affected women.Main Outcome Measure(s): Frequency and distribution of HaeIII and MspI polymorphisms in ER-alpha.Result(s): No significant differences in the frequency of polymorphisms either in intron I or exon I of ER-alpha were found when endometriosis patients were compared with control subjects. Furthermore. the frequency of ER-a polymorphisms within the two different groups of patients with disease was statistically similar. the odds ratio between presence of intron I single-nucleotide polymorphisms (SNP) and endometriosis was 0.904, and the odds ratio between exon I SNP and endometriosis was 0.976.Conclusion(S): the evaluated polymorphisms were not associated with endometriosis.
