About ChiLDREN:
The Cholestatic Liver Disease Consortium (CLiC) is now part of ChiLDREN, the Childhood Liver Disease Research and Education Network. The new and expanded network combines CLiC and the Biliary Atresia Research Consortium (BARC), as well as new studies on cystic fibrosis liver disease. This consolidation seeks to facilitate the discovery of new diagnostics, etiologic, and treatment options for children with rare liver diseases, and those who undergo liver transplantation, and to train the next generation of investigators in rare pediatric liver diseases.
Diseases Researched:
- Alagille syndrome
- Alpha-1-antitrypsindeficiency
- Bile acid synthesis and metabolism defects
- Biliary atresia
- Cystic fibrosis liver disease
- Idiopathic neonatal hepatitis
- Mitochondrial hepatopathies
- Progressive familial intrahepatic cholestasis
