Association between DNMT3L polymorphic variants and the risk of endometriosis-associated infertility.

چکیده
Endometriosis is considered to be an epigenetic disease. It has previously been reported that the DNA methyltransferase 3-like (DNMT3L) rs8129776 single nucleotide polymorphism (SNP) contributes to endometrioma. In the present study, high‑resolution melting curve analysis was used to investigate the risks associated with the DNMT3L c.910‑635A/G (rs8129776), c.832C/T (rs7354779), c.812C/T (rs113593938) and c.344+62C/T (rs2276248) SNPs on stage I‑II endometriosis‑associated infertility. Included in the present study were patients presenting with stage I‑II endometriosis‑associated infertility (n=154) and a control cohort of healthy patients with confirmed fertility (n=383). No significant association between the above‑listed DNMT3L SNPs and the development of endometriosis‑associated infertility was identified. The lowest P‑values generated from trend analysis were observed in the DNMT3L c.832C/T (rs7354779) SNP (Ptrend=0.114). Furthermore, haplotype analyses of the DNMT3L SNPs failed to reveal any risk association between the development of endometriosis‑associated infertility and the above‑listed polymorphisms, even when the SNPs were present in combinations. Finally, a meta‑analysis was performed to examine the association between the DNMT3L rs8129776 SNP and the development of endometrioma, from which no association between the two was identified. On the basis of these results, the present study has demonstrated that variations in the DNMT3L gene do not contribute to stage I-II endometriosis-associated infertility.

Polymorphic variants in vitamin D signaling pathway genes and the risk of endometriosis-associated infertility.
It has recently been reported that vitamin D blood plasma levels are associated with reduced risk of endometriosis. The present study aimed to investigate whether the vitamin D binding protein (GC), vitamin D receptor (VDR), and retinoid X receptor (RXR) gene variants may be genetic risk factors for endometriosis‑associated infertility. The subjects consisted of 154 women with endometriosis‑ass...

Background: The major issue to address in endometriosis etiology is to identify the genetic changes in the disease and their occurrence in different populations. Uncovering these genetic changes may be important in developing potential biomarkers for early diagnosis and prognosis of endometriosis. Among all endometriosis susceptibility genes studied before, convincing association has been found...
