Familial intrahepatic cholestasis is a confusing group of syndromes. Four forms are defined and discussed in detail ("arteriohepatic dysplasia," the Byler syndrome, the THCA syndrome, and Norwegian cholestasis). A comparison of the distinguishing characteristics of these syndromes demonstrates that they share many features, including areflexia, retinal degeneration, and paucity of the intrahepa...

Background: Progressive familial intrahepatic cholestases (PFIC) are a spectrum of autosomal progressive liver diseases developing to end-stage liver disease. ATP8B1 deficiency caused by mutations in ATP8B1 gene encoding a P-type ATPase leads to PFIC1. The gene for PFIC1 has been mapped on a 19-cM region of 18q21-q22, and a gene defect in ATP8B1 can cause deregulations in bile salt transporters...

Background and Aim: Even though there is growing utilization of whole exome or genome sequencing, some patients with cholestatic liver disease do not exhibit any known genetic causes. However, recent studies have identified Ubiquitin Specific Peptidase (USP53) as a potential candidate gene responsible for specific form progressive familial intrahepatic cholestasis (PFIC), PFIC 7. Case Report: W...

Intrahepatic cholestasis represents a heterogeneous group of disorders that begin during childhood, most commonly manifesting as neonatal cholestasis, and lead to ongoing liver dysfunction in children and adults. For children, inherited pathogenic factors of cholestasis have gained increasing attention owing to the rapid development of molecular biology technology. However, these methods have t...
