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.
