The molecular genetics of familial intrahepatic cholestasis

Genetics of familial intrahepatic cholestasis syndromes.

Bile acids and bile salts have essential functions in the liver and in the small intestine. Their synthesis in the liver provides a metabolic pathway for the catabolism of cholesterol and their detergent properties promote the solubilisation of essential nutrients and vitamins in the small intestine. Inherited conditions that prevent the synthesis of bile acids or their excretion cause cholesta...

Progressive Familial Intrahepatic Cholestasis

Severe familial intrahepatic cholestasis.

Odievre, M., Gautier, M., Hadchouel, M., and Alagille, D. (1973). Archives of Disease in Childhood, 48, 806. Severe familial intrahepatic cholestasis. Five cases of intrahepatic cholestasis are reported in 4 families in which 7 other children have had the same disease. Cholestasis, beginning before the age of one year, is notable for the absence of lipid retention, evolving by attacks brought o...

Progressive familial intrahepatic cholestasis

Progressive familial intrahepatic cholestasis (PFIC) refers to a heterogeneous group of autosomal-recessive disorders of childhood that disrupt bile formation and present with cholestasis of hepatocellular origin. The exact prevalence remains unknown, but the estimated incidence varies between 1/50,000 and 1/100,000 births. Three types of PFIC have been identified and associated with mutations ...

Genetics and Molecular Modeling of New Mutations of Familial Intrahepatic Cholestasis in a Single Italian Center

Familial intrahepatic cholestases (FICs) are a heterogeneous group of autosomal recessive disorders of childhood that disrupt bile formation and present with cholestasis of hepatocellular origin. Three distinct forms are described: FIC1 and FIC2, associated with low/normal GGT level in serum, which are caused by impaired bile salt secretion due to defects in ATP8B1 encoding the FIC1 protein and...
