Abstract
Some evidence indicates endometriosis and migraine have a common genetic predisposition in sex-hormone genes, which could have important implications for the treatment of these two heterogenous conditions. To date, the genes responsibility remains unknown. Based on the biological hypothesis that polymorphisms of genes involved in sex-hormone pathways may influence estrogen levels and phenotypes of both disorders, we did a literature search for candidate sex-hormone genes and genes involved in the metabolism of estradiol. The aim was to review the evidence for shared sex-hormone-related polymorphisms between endometriosis and migraine and provide an exhaustive overview of the current literature. We included case-control studies investigating associations between candidate sex-hormone-related genes and the disorders endometriosis and migraine, respectively. Results showed three overlapping sex-hormone-associated polymorphisms in estrogen receptor genes that are associated with both conditions. To confirm possible associations with other sex-hormone genes, larger studies are needed.

Abstract
OBJECTIVE To identify the role of estrogen receptor-beta (ER-β) gene +1730G/A (rs4986938) polymorphisms in recurrent pregnancy loss (RPL). METHODS All relevant case-control studies will be systematically searched in multiple databases including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Internet (CNKI), Wanfang and Cqvip. Both pooled odds rations (ORs) and 95% confidence intervals (CIs) will be used to assess the association between ER-β gene +1730G/A polymorphisms and RPL risk. The publication bias will be evaluated using Egger test. RESULTS ER-β gene +1730G/A variation may be associated with a higher risk of RPL in Caucasian population. CONCLUSIONS The findings of this meta-analysis will provide high-quality evidence for the association between ER-β gene +1730G/A polymorphisms and RPL, facilitating clinical practice and further scientific studies.

Abstract
The pathogenesis of endometriosis is unknown, but some evidence supports a genetic predisposition. The purpose of this study was to evaluate the recent literature on the genetic characterization of women affected by endometriosis and to evaluate the influence of polymorphisms of the wingless-type mammalian mouse tumour virus integration site family member 4 (WNT4), vezatin (VEZT), and follicle stimulating hormone beta polypeptide (FSHB) genes, already known to be involved in molecular mechanisms associated with the proliferation and development of endometriotic lesions in the Sardinian population. Materials and Methods: In order to provide a comprehensive and systematic tool for those approaching the genetics of endometriosis, the most cited review, observational, cohort and case-control studies that have evaluated the genetics of endometriosis in the last 20 years were collected. Moreover, 72 women were recruited for a molecular biology analysis of whole-blood samples—41 patients affected by symptomatic endometriosis and 31 controls. The molecular typing of three single nucleotide polymorphisms (SNPs) was evaluated in patients and controls: rs7521902, rs10859871 and rs11031006, mapped respectively in the WNT4, VEZT and FSHB genes. In this work, the frequency of alleles, genotypes and haplotypes of these SNPs in Sardinian women is described. Results: From the initial search, a total of 73 articles were chosen. An analysis of the literature showed that in endometriosis pathogenesis, the contribution of genetics has been well supported by many studies. The frequency of genotypes observed in the groups of the study population of 72 women was globally coherent with the law of the Hardy–Weinberg equilibrium. For the SNP rs11031006 (FSHB), the endometriosis group did not show an increase in genotypic or allelic frequency due to this polymorphism compared to the control group (p = 0.9999, odds ratio (OR) = 0.000, 95% confidence interval (CI), 0.000–15.000 and p = 0.731, OR = 1639, 95% CI, 0.39–683, respectively, for the heterozygous genotype and the polymorphic minor allele). For the SNP rs10859871 (VEZT), we found a significant difference in the frequency of the homozygous genotype in the control group compared to the affected women (p = 0.0111, OR = 0.0602, 95% CI, 0.005–0.501). For the SNP rs7521902 (WNT4), no increase in genotypic or allelic frequency between the two groups was shown (p = 0.3088, OR = 0.4133, 95% CI, 0.10–1.8 and p = 0.3297, OR = 2257, 95% CI, 0.55–914, respectively, for the heterozygous genotype and the polymorphic minor allele). Conclusion: An analysis of recent publications on the genetics of endometriosis showed a discrepancy in the results obtained in different populations. In the Sardinian population, the results obtained do not show a significant association between the investigated variants of the genes and a greater risk of developing endometriosis, although several other studies in the literature have shown the opposite. Anyway, the data underline the importance of evaluating genetic variants in different populations. In fact, in different ethnic groups, it is possible that specific risk alleles could act differently in the pathogenesis of the disease.

Abstract
This review aimed to critically evaluate the review, observational, cohort, and case-control studies performed so far in order to assess the association between endometriosis and genetics. The search strategies used included an online search of the MEDLINE database and a manual search of relevant publications and reviews. Additional reports were collected by systematically reviewing all references from the retrieved papers. Family studies have long suggested that genetic factors play a role in the etiology of endometriosis. Nevertheless, until now, studies on candidate genes have revealed inconsistent and contradictory evidence, leading to more questions rather than clear answers. It is possible that recent technological improvements in genetic evaluation could allow for a better understanding of the pathogenic mechanisms of endometriosis in the near future.

Abstract
Purpose: To investigate the association between polymorphisms in the genes of estrogen receptor alpha, estrogen receptor beta, and progesterone receptor and the genesis of endometriosis. Methods: Systematic review and meta-analysis of articles published fully in the PubMed database, in Portuguese, English, or Spanish, from 2006 to 2017, using the descriptors: “endometriosis,” “polymorphism,” “ESR1,” “ESR2,” “PROGINS,” “rs9340799,” “rs4986938,” and “rs1042838.” Results: A total of 20 studies were included based on the criterion of search for susceptibility to endometriosis related to polymorphisms of estrogen receptor alpha, estrogen receptor beta, and progesterone receptor genes. Analysis of all polymorphisms found no association with endometriosis. Conclusion: This meta-analysis showed that estrogen receptor alpha, estrogen receptor beta, and progesterone receptor polymorphisms are not related to susceptibility to endometriosis. However, such results may be able to provide more detailed interpretations of how they influence the pathogenesis of endometriosis.

Abstract
STUDY DESIGN A genetic association study of estrogen receptor 2 gene (ESR2) polymorphisms in idiopathic scoliosis (IS). OBJECTIVE To investigate association of the ESR2 polymorphisms with either predisposition to or progression of IS in Central European population. SUMMARY OF BACKGROUND DATA In ESR2 the rs1256120 polymorphism was described to be associated with predisposition to and severity of IS in Chinese population. This observation has not been confirmed in Japanese population. The ESR2 rs4986938 and rs1256049 polymorphisms were described to present association with breast cancer, rheumatoid arthritis, and bone mineral density, however the association with IS has not been evaluated. METHODS Case-control study of 248 females with IS and 243 healthy females was performed. Three single-nucleotide polymorphisms were studied using polymerase chain reaction-restriction fragments length polymorphism technique with the restriction enzymes: AlwNI (C/T rs1256120), AluI (A/G rs4986938), and RsaI (A/G rs1256049). The patients' medical history was evaluated, Cobb angle was measured and surgery rate established. The patients were analyzed in 3 subgroups according to curve progression velocity. RESULTS Neither the genotypes nor alleles distribution showed significant differences between patients with IS and healthy controls. There was no significant difference in genotype or allele frequency. In the AluI site polymorphism a significant difference in mean Cobb angle between genotypes was found: (AA, 31.9° ± 14.2°; AG, 43.2° ± 17.8°; and GG, 38.9° ± 19.0°), P = 0.002. There was significant difference in genotype distribution between patients with moderate (<40°) versus severe (≥40°) scoliosis, P = 0.0011; the minor allele frequency (AA) in recessive model of penetration was over-represented in patients with Cobb angle below 40°, P = 0.0075, odds ratio = 3.65. CONCLUSION No association between ESR2 polymorphism and predisposition to IS was found in Caucasian females. None of the previously reported associations of AlwNI site polymorphism could be confirmed. ESR2 AluI site polymorphism may be associated with curve severity. LEVEL OF EVIDENCE N/A.

Abstract
OBJECTIVE To establish a multilocus model for studying the effect of steroid-related genes on advanced stage endometriosis. MATERIALS AND METHODS A total of 121 patients with advanced stage endometriosis and 171 control women were included. Eighteen single-nucleotide polymorphisms (SNPs) from nine genes (HSD17B1, HSD17B2, HSD17B5, HSD17B6, CYP17, CYP19, ERα, ERβ, and PGR) were genotyped using the TaqMan assays. Logistic regression models were used to evaluate the genetic effects, with adjustment for other covariates. RESULTS Only the presence of the mutant CYP19 (aromatase gene) was associated with a significantly increased risk of endometriosis after adjusting for age, BMI, and parity (p = 0.002, OR = 2.69; 95% CI = 1.44-5.02). No association was ascertained between the other investigated SNPs and endometriosis. CONCLUSION Polymorphisms of the aromatase gene confer susceptibility to advanced stage endometriosis in the Taiwanese Han population.

Abstract
Background Many epidemiological studies have suggested an association between estrogen receptor-beta (ER-β) polymorphisms with endometriosis risk. However, the results of these studies have been inconsistent. In the present study, we performed a meta-analysis to clarify the associations between the ER-β rs4986938 and rs1256049 polymorphisms and endometriosis risk. Methods Eligible publications were retrieved from the PubMed, ISI Web of Science, and several Chinese language databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a random or fixed effect model. Results A total of eight studies (1100 cases/1485 controls) for the rs4986938 polymorphism and four studies (353 cases/450 controls) for the rs1256049 polymorphism were included in this meta-analysis. Regarding the rs4986938 polymorphism, no obvious associations were found for all genetic models when all studies were pooled into the meta-analysis. In the subgroup analyses by ethnicity, study sample size, endometriosis-associated infertility, and stage of endometriosis, a significantly increased risk was observed among mixed populations (dominant model, OR = 2.03, 95% CI = 1.56–2.64) and among cases with endometriosis-associated infertility (dominant model, OR = 1.83, 95% CI = 1.26–2.67). Regarding the rs1256049 polymorphism, no obvious associations were found for all genetic models in the overall population. Subgroup analyses by ethnicity and study sample size revealed that only one study of a mixed population with small sample size showed an increased risk of endometriosis. No publication bias was found in the present study. Conclusions The results of this meta-analysis suggest that the ER-β rs4986938 and rs1256049 polymorphisms may not be associated with endometriosis risk, while the observed increased risk of endometriosis-associated infertility may be due to bias by the inclusion of small-scale studies.

Abstract
Background Endometriosis is a common disease that causes pain and infertility. The heritable predisposition toward endometriosis motivates an interest to identify the genes and genomic variants involved in the pathogenesis of endometriosis. Both genetic and environmental factors contribute to this disease. Here we investigated in Pakistani women the association of endometriosis and single nucleotide polymorphisms (SNP) in genes previously identified in the development of this disease. Methods DNA samples from 52 genetically unrelated endometriosis subjects with endometriosis and 52 randomly selected controls were analyzed by direct sequencing to determine polymorphisms in four genes. These included estrogen receptor alpha (ESR1) (rs2234693 C/T, rs9340799 G/A SNP), estrogen receptor beta (ESR2) (rs4986938 G/A SNP), progesterone receptor (PGR) (rs1042838 G/T, rs10895068 G/A SNPs) and interleukin 10 (IL10) (rs1800871 C/T, rs1800872 C/A and rs1800896 G/A SNPs). Results The allele A at −592, T at −819 and G at −1080 of IL10 and all of the SNPs studied at ESR2 and PGR show strong, statistically significant associations with the disease. However, the genetic variation at ESR1 was distributed similarly among cases and control groups. Conclusion These findings suggest that the functional promoter polymorphism of the IL10 gene, identified by the “ATG” genotype, may contribute to the risk of endometriosis. Genetic variants of ESR2 and PGR gene may also be a risk factor as well as influence the fertility status of patients with endometriosis.

Abstract
A myriad of physiological processes in mammals are influenced by estrogens and the estrogen receptors (ERs), ERα and ERβ. As we reviewed previously, given the widespread role for estrogen in normal human physiology, it is not surprising that estrogen is implicated in the development or progression of a number of diseases. In this review, we are giving a 5-year update of the literature regarding the influence of estrogens on a number of human cancers (breast, ovarian, colorectal, prostate, and endometrial), endometriosis, fibroids, and cardiovascular disease. A large number of sophisticated experimental studies have provided insights into human disease, but for this review, the literature citations were limited to articles published after our previous review (Deroo and Korach in J Clin Invest 116(3):561-570, 2006) and will focus in most cases on human data and clinical trials. We will describe the influence in which estrogen's action, through one of or both of the ERs, mediates the aforementioned human disease states.

Abstract
OBJECTIVE To determine the frequency of the estrogen receptor b gene (ERβ) +1730 G/A polymorphism in infertile women with and without endometriosis and controls. SUBJECTS AND METHODS Case-control study that included 136 women with endometriosis, 69 women without endometriosis and 209 fertile women as controls. The ERβ gene + 1730 G/A polymorphism was identified by RFLP-PCR (Restriction Fragment Length Polymorphism - Polymerase Chain Reaction). RESULTS Genotypes GG, GA and AA of the ERβ gene presented frequencies of 60.3%, 38.2% and 1.5%, respectively, in the women with endometriosis (p < 0.0022). Of the infertile women without endometriosis, 63.8% presented the normal homozygous genotype GG, 30.4% the GA heterozygous genotype, and 5.8% the homozygous mutated genotype AA (p < 0.0275). In the control group, 77.5% presented the normal homozygous genotype GG, 21.1% the heterozygous genotype GA, and 1.4% the homozygous mutated genotype AA. CONCLUSION The data suggest that the estrogen receptor β gene (ERβ) +1730 G/A polymorphism can be associated with risk of infertility and endometriosis-associated infertility.

Abstract
OBJECTIVE To evaluate the relationship between common genetic variation in genes involved in the biosynthesis and signaling of estrogen and progesterone and endometriosis risk. DESIGN Genetic polymorphism analysis. SETTING Population-based case-control study conducted in Group Health Cooperative enrollees in western Washington. PATIENT(S) Women with newly diagnosed, surgically confirmed endometriosis between 1996 and 2001 (n = 256) and age- and reference year-matched female control subjects without a history of endometriosis (n = 567). INTERVENTIONS(S) None. MAIN OUTCOME MEASURE(S) We evaluated the relationship between common genetic variation and endometriosis risk, using gene-based tests and single-variant analysis of genetic polymorphisms in ESR1, ESR2, PGR, CYP17A1, CYP19A1, HSD17B1, HSD17B2, CYP1A1, CYP1A2, COMT, and GSTM1. RESULT(S) The most consistent gene-based association with endometriosis risk was for CYP19A1. We did not find evidence for consistent significant associations between previously reported candidate SNPs in sex hormone-related genes and endometriosis risk. CONCLUSION(S) In summary, we report increased endometriosis risk with CYP19A1 gene-based tests; replication of the association between endometriosis and this gene or gene region is necessary in a larger study population.

Abstract
Endometriosis is a common, chronic gynaecological disease affecting up to 10% of women in their reproductive years. Its aetiology still remains unclear, but evidence indicates genetic factors play a role. We previously identified a region of significant linkage on chromosome 7 in 52 families comprising at least three affected women, stretching ∼6.4 Mb. We screened coding regions and parts of the regulatory regions of three candidate genes with a known role in endometrial development and function-INHBA, SFRP4 and HOXA10-located under or very near the linkage peak, for potential causal mutations using Sanger sequencing. Sequencing was conducted in 47 cases from the 15 families contributing most to the linkage signal (Z(mean) ≥ 1). Minor allele frequencies (MAFs) of observed variants were compared with MAFs from two publicly available reference populations of European ancestry: 60 individuals in HapMap and 150 individuals in the 1000 Genomes Project. A total of 11 variants were found, 5 (45%) of which were common (MAF > 0.05) among the 15 case families and the reference populations (P-values for MAF difference: 0.88-1.00). The remaining six were rare and unlikely to be individually or cumulatively responsible for the linkage signal. The results indicate that the coding regions of these three genes do not harbour mutations responsible for linkage to endometriosis in these families.

BMC Genet 2009; 10:55.

Abstract
BACKGROUND The present study represents the first attempt to functionally characterize two common single nucleotide polymorphisms (SNPs) in the 3'untranslated regions (3'UTRs) of estrogen receptor beta (ERbeta), focusing on the differences between alleles with regard to mRNA stability and translatability. These two ERbeta SNPs have been investigated for association with disease in a large number of reports. RESULTS Here we examined allelic expression in breast tumor samples from heterozygous individuals. A significant difference in mRNA levels of the two alleles was observed for one of the SNPs. A cell model system was employed to further investigate potential molecular effects of the two SNPs. We used a modified plasmid, containing the ERbeta promoter and ERbeta 3'UTRs which include the different alleles of investigated SNPs. Quantitative Real-Time PCR was used to determine mRNA levels after inhibition of transcription by actinomycin D, and a luciferase assay was used to determine protein levels. The obtained results suggested that there was no difference in mRNA stability or translatability between the alleles of investigated SNPs. CONCLUSION Our results indicate that observed associations between ERbeta 3'UTR SNPs and disease susceptibility are due to linkage disequilibrium with another gene variant, rather than the variant itself being the susceptibility factor.

Abstract
BACKGROUND The purpose of this study was to investigate the potential association of the C627T polymorphism in the interleukin-2 receptor beta gene (IL-2R beta) with the risk of endometriosis in Korean women. METHODS Two hundred and thirty-seven women with surgically or histologically diagnosed endometriosis of stages III and IV were recruited for this study, and 164 patients with no evidence of endometriosis diagnosed by laparoscopy or laparotomy served as controls. The C627T polymorphism of the IL-2R beta was assessed using the TaqMan allelic discrimination assay. Chi2 analysis was used to examine any differences in genotype distributions and allele frequencies of the IL-2R beta C627T polymorphism between the endometriosis cases and the controls. RESULTS There was no statistically significant difference in the frequency of the IL-2R beta C627T polymorphism between the endometriosis patients and the controls (28.7% C/C, 48.1% C/T and 23.2% T/T versus 29.3, 44.5 and 26.2%, respectively, P = 0.72) or in the T allele frequencies (47.3 versus 48.5%, respectively, P = 0.73). Even when the endometriosis cases were subdivided into stages III and IV, no statistically significant differences in genotype distributions or allele frequencies were observed among the three groups. CONCLUSIONS Contrary to the recent data reported in a Taiwanese population, our results suggest that the C627T polymorphism of the IL-2R beta gene may not be associated with the risk of endometriosis in the Korean population.

Abstract
OBJECTIVE To investigate whether the +1730 G/A polymorphism in the estrogen receptor (ER)-beta gene is associated with susceptibility to polycystic ovary syndrome (PCOS). DESIGN Case-control study. SETTING University Department of Obstetrics and Gynecology. PATIENT(S) Women with (n = 138) or without (n = 290) PCOS. INTERVENTION(S) Genotyping was performed by polymerase chain reaction-restriction fragment-length polymorphism analysis. MAIN OUTCOME MEASURE(S) Genotype distribution and allele frequency of the +1730 G/A polymorphism in the ER-beta gene. RESULT(S) There was a significant difference in the genotype distribution between the patients with PCOS and controls (non-GG rates were 22.1% for patients with PCOS and 36.6% for controls). There was also a significant difference in the G and A allele frequencies between these two groups (11.7% in patients vs. 19.1% in controls with A allele). But in patients with PCOS there were no significant differences in the serum levels of hormones, biochemical variables, or ovarian morphology between GG and non-GG genotypes. CONCLUSION(S) The ER-beta gene +1730 G/A polymorphism may be associated with pathophysiologic aberrancies involved in PCOS.

Abstract
Estrogen hormones play critical roles in the regulation of many tissue functions. The effects of estrogens are primarily mediated by the estrogen receptors (ER) alpha and beta. ERs are ligand-activated transcription factors that regulate a complex array of genomic events that orchestrate cellular growth, differentiation and death. Although many factors contribute to their etiology, estrogens are thought to be the primary agents for the development and/or progression of target tissue malignancies. Many of the current modalities for the treatment of estrogen target tissue malignancies are based on agents with diverse pharmacology that alter or prevent ER functions by acting as estrogen competitors. Although these compounds have been successfully used in clinical settings, the efficacy of treatment shows variability. An increasing body of evidence implicates ERalpha polymorphisms as one of the contributory factors for differential responses to estrogen competitors. This review aims to highlight the recent findings on polymorphisms of the lately identified ERbeta in order to provide a functional perspective with potential pharmacogenomic implications.

Abstract
BACKGROUND Endometriosis has a strong genetic component, and numerous genetic studies have been reported. METHODS We have systematically reviewed these studies and included 114 in our final selection. RESULTS We found no consistent evidence linking endometriosis with specific polymorphisms in genes encoding inflammatory mediators, proteins involved in sex steroid metabolism, vascular function and tissue remodelling. Although a number of polymorphisms have been associated with endometriosis in selected populations, the associations have not been independently confirmed, either because only single studies were carried out on these markers/genes or because other studies reported no association. The most solid evidence linking specific polymorphisms to endometriosis came from studies investigating glutathione-S-transferase, a phase II detoxification enzyme. Carriage of the GSTT1 null deletion variant showed consistent association with endometriosis with a 29% increased risk; however, it cannot be excluded that this result was due to publication bias, and this association should be independently confirmed in large-scale, well-designed case–control studies. CONCLUSIONS The evidence of an association between genetic polymorphisms and endometriosis is weak. Carriage of the GSTT1 null deletion may moderately increase the risk of this disease. We suggest that the methodology of association studies should be improved in order to identify and validate associations in endometriosis.
