This study examined whether ICAM-1 polymorphisms K469E (rs5498) and G241R (rs1799969) and the IL-6 polymorphism G634C (rs1800796) are associated with endometriosis susceptibility in 200 Brazilian women (100 with endometriosis and 100 controls), genotyped using PCR-RFLP. The authors found no significant differences in genotype frequencies between control and endometriosis groups for G634C (p = 0.61) and K469E (p = 0.22), and no significant differences across disease stages I–II versus III–IV for either SNP (p = 0.63 and p = 0.24). They also reported that all participants were wild homozygotes for the G241R polymorphism. The paper concludes that these polymorphisms are not associated with increased endometriosis susceptibility in this population. This paper is centrally about endometriosis — it tests associations between ICAM-1 and IL-6 gene polymorphisms and endometriosis risk in Brazilian women.

Abstract

PurposeThis study investigated the possibility of K469E (rs5498) and G241R (rs1799969) polymorphisms, in ICAM-1 gene, and G634C (rs1800796), in IL-6 gene, being associated with the occurrence of endometriosis in a sample of Brazilian women.MethodsWe genotyped 200 women (100 in control group and 100 in endometriosis group) by PCR-RFLP technique for G634C, K469E, and G241R polymorphisms.ResultsNo significant difference was observed in genotypic frequency between control and endometriosis groups for G634C and K469E polymorphisms (p = 0.61 and p = 0.22, respectively). In addition, no significant difference between stages I-II and III-IV of the disease was found for both SNPs (p = 0.63 and p = 0.24, respectively). All individuals were wild homozygotes for G241R polymorphism.ConclusionThis study suggests that polymorphisms K469E, G241R, and G634C are not associated with increased susceptibility to endometriosis in Brazilian women.

Abstract

Purpose This study investigated the possibility of K469E (rs5498) and G241R (rs1799969) polymorphisms, in ICAM-1 gene, and G634C (rs1800796), in IL-6 gene, being associated with the occurrence of endometriosis in a sample of Brazilian women.

Methods

We genotyped 200 women (100 in control group and 100 in endometriosis group) by PCR-RFLP technique for G634C, K469E, and G241R polymorphisms.

Results

No significant difference was observed in genotypic frequency between control and endometriosis groups for G634C and K469E polymorphisms (p = 0.61 and p = 0.22, respectively). In addition, no significant difference between stages I-II and III-IV of the disease was found for both SNPs (p = 0.63 and p = 0.24, respectively). All individuals were wild homozygotes for G241R polymorphism.

Conclusion

This study suggests that polymorphisms K469E, G241R, and G634C are not associated with increased susceptibility to endometriosis in Brazilian women. Similar content being viewed by others
