Neonatal sclerosing cholangitis is a rare biliary tract disease characterised by severe neonatal-onset cholangiopathy with patent bile ducts.4
Some extrahepatic signs such as ichthyosis-like skin lesions and renal disease may be present.4
Some cases have a genetic origin with an autosomal recessive pattern of inheritance (mutation in the CLDN1 and DCDC2 genes).34,35
Diagnosis
Diagnosis is usually achieved by:
- Intraoperative cholangiogram and live biopsy36
- Sequencing of CLDN1 and DCDC2 genes34,35
