DESCRIPTION (provided by applicant): Endometriosis is a poorly understood gynecologic condition defined as the presence of endometrial tissue at ectopic sites. This condition is characterized by severe pelvic pain, dyspareunia, dysmenorrhea, and infertility. Endometriosis continues to incapacitate and affect the well being, productivity, and lifestyle of millions of women, whilst imposing a challenge to medical doctors and researchers alike. The cause of endometriosis remains elusive, although environmental, immunological and genetic factors have been implicated. The limited treatments available are not curative, and definitive diagnosis requires surgery, since there are no specific diagnostic tests for this disease. We have been studying the molecular and genetic aspects of endometriosis in Puerto Rico, with the purpose of filling an important gap in the knowledge of this disease in general, and also as its applies to the Hispanic population in particular. Preliminary studies in our laboratory have shown that previously reported genetic associations to endometriosis do not hold true in our population. These findings highlight the importance of carrying out association studies in different populations, since genetic variations and their involvement in disease susceptibility are likely to vary across ethnic backgrounds. Also, we have observed that genetic associations differ in patients with and without a family of endometriosis. Finally, we have used DNA microarrays, subtractive hybridization and genetic linkage analysis to identify candidate genes/genomic regions which potentially represent susceptibility loci for endometriosis. We hypothesize that genetic variations in candidate genes are associated with susceptibility to endometriosis. Also, we hypothesize that genetic associations differ in patients with familial versus sporadic endometriosis. The main goal of the present proposal, therefore, is to elucidate the mechanisms involved in the genetic susceptibility to endometriosis in a Puerto Rican population, and to determine if those mechanisms vary according to family history status. Identification of such variations is of critical importance to better understand the etiology of endometriosis, to design specific non-invasive diagnostic tests and, ultimately, to develop a cure for this incapacitating condition. Due to important links between endometriosis and infertility, pregnancy loss and ectopic pregnancy, the information uncovered by these studies will greatly impact the field of reproductive science, a target issue addressed in the Healthy People 2010 report (9-12).

描述（由申请人提供）：子宫内膜异位症是一种贫困的妇科疾病，定义为在异位部位存在子宫内膜组织。这种疾病的特征是严重的骨盆疼痛，肌肉麻木，痛经和不育。子宫内膜异位症继续丧失和影响数百万妇女的福祉，生产力和生活方式，同时对医生和研究人员构成挑战。子宫内膜异位症的原因仍然难以捉摸，尽管已经涉及环境，免疫学和遗传因素。可用的有限治疗方法无法治愈，并且确定的诊断需要手术，因为该疾病没有特定的诊断检查。我们一直在研究波多黎各的子宫内膜异位症的分子和遗传方面，目的是填补一般的这种疾病知识的重要空白，也尤其适用于西班牙裔人群。我们实验室的初步研究表明，先前报道的子宫内膜异位症的遗传关联在我们的人群中并不成立。这些发现突出了在不同人群中进行关联研究的重要性，因为遗传变异及其参与疾病易感性可能会在种族背景下有所不同。此外，我们已经观察到，有或没有子宫内膜异位症家族的患者遗传关联有所不同。最后，我们使用了DNA微阵列，减法杂交和遗传连锁分析来识别候选基因/基因组区域，这些区域可能代表了子宫内膜异位症的易感基因座。我们假设候选基因的遗传变异与子宫内膜异位症的敏感性有关。此外，我们假设家族性子宫内膜异位症患者的遗传关联不同。因此，本提案的主要目的是阐明波多黎各人口中子宫内膜异位症的遗传敏感性所涉及的机制，并确定这些机制是否根据家族史状况而变化。对这种变化的识别对于更好地了解子宫内膜异位症的病因，设计特定的非侵入性诊断测试以及最终为这种无能为力的状况开发一种治愈方法至关重要。由于子宫内膜异位症与不育之间的重要联系，妊娠丧失和异位妊娠之间，这些研究发现的信息将极大地影响生殖科学领域，这是《健康人》 2010年的《 2010年健康人》报告（9-12）。
