Hepatic Histopathology in Urea Cycle Disorders
Baylor College of Medicine
Summary
This is a multi-site, retrospective chart review as well as a prospective study to evaluate histopathologic findings in liver samples from individuals with any UCD diagnosis. This study will be conducted at all Urea Cycle Disorders Consortium (UCDC) sites: Baylor College of Medicine in Houston, TX and Children's National Medical Center in Washington D.C.
Description
Urea cycle disorders (UCDs) are among the most common inborn errors of liver metabolism. With early diagnosis and improved treatments, the survival of individuals with UCDs has improved, and this improved survival has led to unmasking of some long-term complications such as hepatic dysfunction and progressive fibrosis in a subset of patients. Hepatic complications in UCDs are quite variable and dependent upon the specific metabolic defect.
