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 ...

Mutations in the MDR3 gene cause progressive familial intrahepatic cholestasis.

Class III multidrug resistance (MDR) P-glycoproteins (P-gp), mdr2 in mice and MDR3 in man, mediate the translocation of phosphatidylcholine across the canalicular membrane of the hepatocyte. Mice with a disrupted mdr2 gene completely lack biliary phospholipid excretion and develop progressive liver disease, characterized histologically by portal inflammation, proliferation of the bile duct epit...

Cholecystoappendicostomy for progressive familial intrahepatic cholestasis.

We report a rare case of progressive familial intrahepatic cholestasis type 2 from India. The diagnosis was confirmed on the basis of gene mutation analysis. The child had intense pruritus refractory to conventional medical management. As liver biopsy did not reveal any cirrhosis, partial external biliary diversion was considered as an alternative to liver transplant. We performed cholecystoapp...

Locus heterogeneity in progressive familial intrahepatic cholestasis.

Progressive familial intrahepatic cholestasis (PFIC or Byler disease) is a rare autosomal recessive form of severe and fatal cholestatic liver disease. A locus for PFIC has recently been mapped to chromosome 18q21-q22 in the original Byler pedigree. This region harbours the locus for a related phenotype, benign recurrent intrahepatic cholestasis (BRIC), suggesting that these traits are allelic....
