Hepatic Histopathology in Urea Cycle Disorders

Hepatic Histopathology in Urea Cycle Disorders

Official Title

Hepatic Histopathology in Urea Cycle Disorders

Brief 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.
    

Detailed 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.
