气管、食道和出生缺陷(TED)发生在气管和食道分离后。
常见的胎盘是在胎儿早期发育的过程中被打乱的。在出生时,TED通常是在没有产前检查的情况下出现的。
诊断:如果不纠正,TED可能会扰乱正常的呼吸和/或喂奶,通常会危及生命。
即使在手术矫正的情况下,他们也经常与长期的心脏合并症有关。
令人信服的证据表明,TED是一种主要的遗传基因成分,其病因在很大程度上是未知的。大约有40%的候选人。
突变也没有被认为与TED有不同程度的信心,但这些基因中只有十几个与突变有关。
他们已经在动物模型中得到了验证,即使在那时,他们用来监管这些动物的发展和机制也很糟糕。
明白了。我们的前提是,没有任何独特的、未经研究的基因突变会导致TED。
这些基因在不同的发育途径中发挥作用,以进一步确定不同的TED解剖结构和组织学表型。
并最终决定了这些患者的临床和病理转归。加深了我们对TED的临床和病理特征的了解。
由于缺乏一份详细的、大规模的遗传学、解剖学、医学和临床医学调查报告,这一问题一直受到阻碍。
因此,这项研究项目的主要目标是进一步提高我们对人类遗传学和遗传物质的认识。
探讨气管、食道及出生缺陷(TEDS)的解剖学基础,以期提高诊断水平,确定相关因素。
这将影响患者的预后,并推动治疗和战略的制定。第二个目标目标被认为是实现该目标的催化剂。
发展生物生物学将通过建立一个更全面的生物数据库的创建计划,在第二季度和第三季度的两个项目中进行研究。
整合组织学和解剖学表型、基因分型、基因和临床预后数据。

英文摘要
Summary, Project 1
Tracheal esophageal birth defects (TEDs) occur when the separation of the trachea and esophagus from the
common foregut is disrupted during early fetal development. TEDs often present at birth without a prenatal
diagnosis and if left uncorrected, TEDs disrupt proper breathing and/or feeding and are usually life threatening.
Even when corrected surgically, they are often associated with long-term comorbidity. Although there is
compelling evidence for a major genetic component, the etiology of TEDs is largely unknown. About 40 candidate
mutations have been associated with TEDs with varying degrees of confidence, but only a dozen of these genes
have been validated in animal models and even then the development mechanisms they regulate are poorly
understood. Our Premise is that there are unique unstudied genetic mutations that cause TEDs and that
these act in distinct developmental pathways to determine the TED anatomic and histological phenotype
and ultimately the clinical outcome of these patients. Our understanding of the clinical pathology of TEDs
has been hampered by the lack of a detailed large scale genetic, anatomic, and clinical investigation of this
patient population. Therefore, the primary goal of this project is to improve our understanding of the genetic and
anatomic basis of tracheal esophageal birth defects (TEDs) in order to enhance diagnosis, determine factors
that influence prognosis and advance treatment strategies. The second goal is to serve as catalyst for the
developmental biology studies in projects 2 and 3 through the creation of a comprehensive database that will
integrate histological and anatomic phenotype, genotype, and clinical outcome data.
Aim 1: Identify candidate causative mutations in patients with TEDs using trio genomic sequencing of TED
patients and their parents.
Aim 2: Investigate the esophageal, tracheal, mediastinal and pulmonary anatomy in patients with TEDs
before and after surgical repair.
Aim 3: Create a multi-center TED registry that integrates a detailed description of the clinical and anatomic
phenotype, genotype, surgical repair strategy, and long term clinical outcome in TED patients.
