Abstract
OBJECTIVE The follicle-stimulating hormone subunit beta gene rs10835638 variant (c.-211G>T) may have detrimental effects on fertility and protective effects against endometriosis. A case-control analysis was performed, aiming to investigate the possible relationship between this variant and the development and/or progression of endometriosis. METHODS This study included 326 women with endometriosis and 482 controls without endometriosis, both confirmed by inspection of the pelvic cavity during surgery. Genotyping was performed using a TaqMan real-time polymerase chain reaction assay. Genotype and allele frequencies and genetic models were compared between the groups. RESULTS The genotype and allele frequencies of the rs10835638 variant did not differ between women with and those without endometriosis. Subdividing the endometriosis group into fertile and infertile groups did not result in a significant difference in these frequencies. However, the subgroup with minimal/mild endometriosis had a higher frequency of the GT genotype than the Control Group, regardless of fertility. The T allele was significantly more common in women with minimal/mild endometriosis than in the Control Group in the recessive model. CONCLUSION The T allele is associated with the development of minimal/mild endometriosis in Brazilian women.

Abstract
BACKGROUND Endometriosis is a common, chronic disease among fertile-aged women. Disease course may be highly invasive, requiring extensive surgery. The etiology of endometriosis remains elusive, though a high level of heritability is well established. Several low-penetrance predisposing loci have been identified, but high-risk susceptibility remains undetermined. Endometriosis is known to increase the risk of epithelial ovarian cancers, especially of endometrioid and clear cell types. Here, we have analyzed a Finnish family where four women have been diagnosed with surgically verified, severely symptomatic endometriosis and two of the patients also with high-grade serous carcinoma. RESULTS Whole-exome sequencing revealed three rare candidate predisposing variants segregating with endometriosis. The variants were c.1238C>T, p.(Pro413Leu) in FGFR4, c.5065C>T, p.(Arg1689Trp) in NALCN, and c.2086G>A, p.(Val696Met) in NAV2. The only variant predicted deleterious by in silico tools was the one in FGFR4. Further screening of the variants in 92 Finnish endometriosis and in 19 endometriosis-ovarian cancer patients did not reveal additional carriers. Histopathology, positive p53 immunostaining, and genetic analysis supported the high-grade serous subtype of the two tumors in the family. CONCLUSIONS Here, we provide FGFR4, NALCN, and NAV2 as novel high-risk candidate genes for familial endometriosis. Our results also support the association of endometriosis with high-grade serous carcinoma. Further studies are required to validate the findings and to reveal the exact pathogenesis mechanisms of endometriosis. Elucidating the genetic background of endometriosis defines the etiology of the disease and provides opportunities for expedited diagnostics and personalized treatments.

Abstract
Endometriosis is a common benign gynaecological disorder, which has an increased prevalence amongst twins and first degree relatives of affected individuals. Here we describe a case of remarkable resemblance in the distribution of deep infiltrating endometriosis related to the bowel in a monozygotic twin pair. We provide a literature review of studies of endometriosis in twins. We propose that genetic factors influence the nature and distribution of the disease, while environmental factors may affect the severity.

Abstract
Endometriosis-associated pain and the mechanisms responsible for its initiation and persistence are complex and difficult to treat. Endometriosis-associated pain is experienced as dysmenorrhea, cyclical pain related to organ function including dysuria, dyschezia and dyspareunia, and persistent pelvic pain. Pain symptomatology correlates poorly with the extent of macroscopic disease. In addition to the local effects of disease, endometriosis-associated pain develops as a product of peripheral sensitization, central sensitization and cross sensitization. Endometriosis-associated pain is further contributed to by comorbid pain conditions, such as bladder pain syndrome, irritable bowel syndrome, abdomino-pelvic myalgia and vulvodynia. This article will review endometriosis-associated pain, its mechanisms, and its comorbid pain syndromes with a view to aiding the clinician in navigating the literature and terminology of pain and pain syndromes. Limitations of our current understanding of endometriosis-associated pain will be acknowledged. Where possible, commonalities in pain mechanisms between endometriosis-associated pain and comorbid pain syndromes will be highlighted.

The Impact of FSHR Gene Polymorphisms Ala307Thr and Asn680Ser in the Endometriosis Development. DNA Cell Biol 2018; 37:584-591.

Abstract
Endometriosis is an estrogen-dependent inflammatory disease that affects a large number of women in reproductive age. Follicle-stimulating hormone (FSH) plays a role in steroidogenesis and acts through a transmembrane glycoprotein, FSH receptor (FSHR). Polymorphisms in FSHR gene were previously associated with variability in FSH serum level and reproductive outcomes, but its relation with endometriosis has not been clarified and demonstrated conflicting results, ranging from strong links to no association to endometriosis. Inspired by these findings, we aimed to investigate the influence of FSHR Ala307Thr and Asn680Ser polymorphisms in the risk of endometriosis development and/or progression and the status of fertility in 352 women with endometriosis and 510 fertile controls. Single-marker analysis revealed no significant difference for both Ala307Thr and Asn680Ser polymorphisms between overall endometriosis and control group. However, when the endometriosis group was subdivided according to fertility status and disease stage, a positive association was found between 680Ser/Ser or GG genotype of the Asn680Ser polymorphism and fertile women with endometriosis (p = 0.004). Combined alleles of FSHR polymorphisms revealed that "GG/307Ala680Ser" was more frequently found in fertile women with endometriosis (haplotype frequency of 45.4% in fertile women with endometriosis and 38.3% in controls, p = 0.041). The combined alleles of FSHR polymorphisms disclosed that "GG/307Ala680Ser" was more frequently found in fertile women with endometriosis (haplotype frequency of 45.4% in fertile women with endometriosis and 38.3% in controls, p = 0.049), while "GA/307Ala680Asn" haplotype was less frequently found in endometriosis group (haplotype frequency of 6.5% in cases and 11.9% in controls, p = < 0.001), regardless of fertility status and stage of the disease. The findings suggest that 680Ser-Ser/GG genotype and "GG/307Ala680Ser" haplotype increase the risk of endometriosis in fertile women, while "GA/307Ala680Asn" haplotype decreases the risk of endometriosis development and progression.
