No association of AhR gene 1661G/A and ARNT gene 567G/C polymorphisms with endometriosis in southern Han Chinese women / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the association between the arylhydrocarbon receptor gene (AhR) 1661G/A or arylhydrocarbon nuclear translocatorgene (ARNT) 567G/C polymorphism and endometriosis in southern Han Chinese women.</p><p><b>METHODS</b>The polymorphisms of AhR gene 1661G/Aand ARNT gene 567G/C in 431 cases of endometriosis and 499 healthy women were genotyped by fluorescence quantitative PCR-based high resolution melting.</p><p><b>RESULTS</b>The frequencies of genotypes AA, AG, GG and alleles A and G in controls were 12.0%, 41.9%, 46.1%, 33.0% and 67.0%, respectively, which were not significantly different from those in patients with endometriosis (9.7%, 44.6%, 45.7%, 32.0% and 68.0%, respectively). The genotype frequencies of GG, GC, CC and alleles C and G in controls (15.6 %, 51.7%, 32.7%, 58.5%, 41.5%) were not significantly different from those in patients with endometriosis (13.5%, 47.8%, 38.7%, 62.6%, 37.4%), either. And no interaction of AhR 1661G/A and ARNT 567G/C on endometriosis was found.</p><p><b>CONCLUSION</b>No association between AhR 1661G/A and ARNT 567G/C genetic polymorphisms and endometriosis was found in the southern Han Chinese women in this study.</p>
