Brief Summary:
The specific aims of this study are (1) to determine the clinical phenotypes and natural history of hepatic RC and FAO disorders, (2) to determine the correlation between genotype and phenotype, (3) to determine if circulating biomarkers reflect diagnosis and predict liver disease progression and survival with the native liver, (4) to determine the clinical outcome of these disorders following liver transplantation, and (5) to develop a repository of serum, plasma, urine, tissue and DNA specimens that will be used in ancillary studies. To accomplish these aims, the ChiLDReN investigators at clinical sites (currently 9 sites) will prospectively collect defined data and specimens in a uniform fashion at fixed intervals in a relatively large number of subjects. Clinical information collected from subjects and their parents will enhance the potential for meaningful research in these disorders. A biobank of previously collected subject specimens and DNA samples will be established for use in ancillary studies to be performed in addition to this study.
Detailed Description:
This study will be conducted as part of the NIH-supported Childhood Liver Disease Research and Education Network (ChiLDREN). ChiLDREN is investigating rare cholestatic liver diseases of childhood: alpha-1 antitrypsin deficiency (A1AT), Alagille's Syndrome (AGS), progressive familial intrahepatic cholestasis (PFIC), bile acid synthesis defects and mitochondrial hepatopathies (all previously studied by the Cholestatic Liver Disease Consortium \[CLiC\]); biliary atresia (previously studied by the Biliary Atresia Research Consortium \[BARC\]); neonatal hepatitis; and cystic fibrosis liver disease, which is studied by a new branch of ChiLDREN known as the Cystic Fibrosis Liver Disease (CFLD) Network.
In this protocol, mitochondrial hepatopathies in children and young adults will be investigated. The focus will be on respiratory chain defects (RC) and defects of fatty acid oxidation (FAO). There is little known about the full spectrum of severity and long-term natural history of mitochondrial hepatopathies. Moreover, these disorders have not been subject to prospective, rigorous clinicopathological scrutiny.
