Endometriosis is a common gynaecological disease associated with severe pelvic pain and sub-fertility. There is considerable debate whether different endometriosis stages represent disease progression, or whether moderate-severe (rAFS III/I…

The impact of erroneous genotypes having passed standard quality control (QC) can be severe in genome-wide association studies, genotype imputation, and estimation of heritability and prediction of genetic risk based on single nucleotide po…

Endometriosis is a common gynecological disease associated with pelvic pain and subfertility. We conducted a genome-wide association study (GWAS) in 3,194 individuals with surgically confirmed endometriosis (cases) and 7,060 controls from A…

Endometriosis can be difficult to diagnose clinically and models that use symptoms to predict whether the disease is present or not are based on limited patient populations. Endometriosis also influences health-related quality of life, but …

Extracting DNA from formalin-fixed and paraffin-embedded (FFPE) tissue remains a challenge, despite numerous attempts to develop a more effective method. Polymerase chain reaction (PCR) success rates with DNA extracted using current methods…

Endometriosis is an estrogen-dependent disorder where endometrial tissue forms lesions outside the uterus. Endometriosis affects an estimated 10% of women in the reproductive-age group, rising to 30% to 50% in patients with infertility and/…

Endometriosis is a complex disease, caused by both genetic and environmental factors and their interaction. Finding causative genes for endometriosis through candidate gene association studies has been largely unsuccesful, because a) they r…

OBJECTIVE: To investigate whether the eNOS gene influences the risk of developing endometriosis in south Indian women. STUDY DESIGN: The single nucleotide polymorphism, Glu298Asp, in exon7 of the eNOS gene was tested for association in a c…

BACKGROUND: Genetic variation contributes to the risk of developing endometriosis. This review summarizes gene mapping studies in endometriosis and the prospects of finding gene pathways contributing to disease using the latest genome-wide …

OBJECTIVE: To determine the relationship between disease severity and patient characteristics in endometriosis. DESIGN: Cross-sectional study of self-reported survey data. SETTING: Academic research setting. PATIENT(S): One thousand wome…

Endometriosis has a genetic component, and significant linkage has been found to a region on chromosome 10q. Two candidate genes, EMX2 and PTEN, implicated in both endometriosis and endometrial cancer, lie on chromosome 10q. We hypothesized…

BACKGROUND: Vascular endothelial growth factor (VEGF) concentration in endometriosis patients is higher than controls, in serum and ascites, suggesting that VEGF may play an important role in the pathogenesis of endometriosis. In this study…

This article reports the findings of a population-based study in New Zealand that investigated comparative well-being, comorbidity, and the impact of chronic pelvic pain (CPP) on activities. Chronic pelvic pain was defined as lower abdomina…
