Description
Background and aims: Polycystic ovary syndrome (PCOS) is a common endocrine disorder that affects women in their child-bearing age, and is often associated with insulin resistance and type 2 diabetes (T2DM). Given the overlap between PCOS and T2DM, we investigated the association of transcription factor-7-like 2 (TCF7L2) variants rs4506565, rs7903146, rs12243326, and rs12255372 with the susceptibility to PCOS. Subjects and methods: Study subjects comprised 119 Tunisian women with PCOS (mean age 29.8. ±. 4.7. years), and 150 control women (mean age 30.6. ±. 5.9. years). TCF7L2 genotyping was done by the allelic discrimination/real-time PCR method. Results: Minor allele frequencies (MAFs) of rs4506565 (P= 0.61), rs7903146 (P= 0.68), rs12243326 (P= 0.56), and rs12255372 (P= 0.60) were comparable between PCOS cases and control subjects. As the four tested TCF7L2 variants were in linkage disequilibrium, 4-locus (rs4506565, rs7903146, rs12243326, rs12255372) haplotype analysis demonstrated that haplotype 2111 was initially negatively associated with PCOS [. P= 0.035; OR (95% CI). = 0.13 (0.02-0.85)], which was later lost upon correcting for multiple comparisons [. Pc= 0.248]. Conclusion: Our data suggest that there is weak or no contribution of TCF7L2 gene polymorphism to PCOS in Tunisian women. Further studies with larger samples are necessary to confirm this observation. © 2013 Elsevier B.V.
