A functional classification ofABCB4variations causing progressive familial intrahepatic cholestasis type 3

Progressive Familial Intrahepatic Cholestasis

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 ...

Progressive Familial Intrahepatic Cholestasis - A Case Report

Introduction Progressive familial intrahepatic cholestasis (PFIC) represents a group of disorders which usually begin in the first months of life and progress to cirrhosis before the end of second decade. The disease occurs due to a defect in bile acid transport leading to cholestasis and resultant hepatocelluler injury1-3. Recent molecular and genetic studies have identified genes responsible ...

Functional characterization of ABCB4 mutations found in progressive familial intrahepatic cholestasis type 3

Multidrug resistance 3 (MDR3), encoded by the ATP-binding cassette, subfamily B, member 4 gene (ABCB4), localizes to the canalicular membrane of hepatocytes and translocates phosphatidylcholine from the inner leaflet to the outer leaflet of the canalicular membrane. Progressive familial intrahepatic cholestasis type 3 (PFIC3) is a rare hepatic disease caused by genetic mutations of ABCB4. In th...

Pancreatic adenocarcinoma in type 2 progressive familial intrahepatic cholestasis

BACKGROUND BSEP disease results from mutations in ABCB11, which encodes the bile salt export pump (BSEP). BSEP disease is associated with an increased risk of hepatobiliary cancer. CASE PRESENTATION A 36 year old woman with BSEP disease developed pancreatic adenocarcinoma at age 36. She had been treated with a biliary diversion at age 18. A 1.7 x 1.3 cm mass was detected in the pancreas on ab...
