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 ...
متن کاملMutations 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...
متن کاملProgressive Familial Intrahepatic Cholestasis – Clinical, Biochemical, Genetic and Histopathological Aspects
In the early 1980’s, most cases of neonatal cholestasis (often referred to as neonatal hepatitis) remained unexplained. By today, many of these diseases have been characterized in detail. Progressive familial intrahepatic cholestasis (PFIC) is one of these cholestatic entities with early onset, where new techniques in genetics and molecular biology have contributed substantially to our understa...
متن کاملLocus 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....
