ABSTRACT
<p><b>OBJECTIVE</b>To assess the possible association between gene mutation of cytochrome P450 1A1(CYP1A1) in exon 7 A4889G locus and the susceptibility to endometriosis (EM).</p><p><b>METHODS</b>Allele specific-polymerase chain reaction method was used to analyze gene mutation in exon 7 A4889G locus of CYP1A1 in 76 patients with endometriosis and 80 healthy controls.</p><p><b>RESULTS</b>The frequency of allele G on A4889G locus of CYP1A1 gene showed a significant difference between the study cohort and the control group (Chi2=7.498, P<0.01), with an odds ratio of 1.957. Statistically significant difference in the frequencies of genotypes AA, AG and GG was observed between the two groups (Chi2=6.915, P<0.05). Individuals with homozygotes for G allele were at higher risk of suffering from EM when compared against those with homozygotes for A allele, the odds ratio being 3.437 (Chi2=5.430, P<0.05).</p><p><b>CONCLUSION</b>The above results suggest that gene mutation of CYP1A1 in exon 7 A4889G locus might be a genetic susceptible factor of endometriosis. The mutation allele of CYP1A1 gene appears to increase the risk of endometriosis.</p>
