Genetics Home Reference : ²⁵ Progressive familial intrahepatic cholestasis (PFIC) is a disorder that causes progressive liver disease, which typically leads to liver failure. In people with PFIC, liver cells are less able to secrete a digestive fluid called bile. The buildup of bile in liver cells causes liver disease in affected individuals. Signs and symptoms of PFIC typically begin in infancy and are related to bile buildup and liver disease. Specifically, affected individuals experience severe itching, yellowing of the skin and whites of the eyes (jaundice), failure to gain weight and grow at the expected rate (failure to thrive), high blood pressure in the vein that supplies blood to the liver (portal hypertension), and an enlarged liver and spleen (hepatosplenomegaly). There are three known types of PFIC: PFIC1, PFIC2, and PFIC3. The types are also sometimes described as shortages of particular proteins needed for normal liver function. Each type has a different genetic cause. In addition to signs and symptoms related to liver disease, people with PFIC1 may have short stature, deafness, diarrhea, inflammation of the pancreas (pancreatitis), and low levels of fat-soluble vitamins (vitamins A, D, E, and K) in the blood. Affected individuals typically develop liver failure before adulthood. The signs and symptoms of PFIC2 are typically related to liver disease only; however, these signs and symptoms tend to be more severe than those experienced by people with PFIC1. People with PFIC2 often develop liver failure within the first few years of life. Additionally, affected individuals are at increased risk of developing a type of liver cancer called hepatocellular carcinoma. Most people with PFIC3 have signs and symptoms related to liver disease only. Signs and symptoms of PFIC3 usually do not appear until later in infancy or early childhood; rarely, people are diagnosed in early adulthood. Liver failure can occur in childhood or adulthood in people with PFIC3.

MalaCards based summary : Progressive Familial Intrahepatic Cholestasis, also known as cholestasis, intrahepatic, familial, progressive, is related to cholestasis, progressive familial intrahepatic, 5 and cholestasis, progressive familial intrahepatic, 4. An important gene associated with Progressive Familial Intrahepatic Cholestasis is ABCB11 (ATP Binding Cassette Subfamily B Member 11), and among its related pathways/superpathways are Bile secretion and Cholesterol metabolism. The drugs Liver Extracts and Bile Acids and Salts have been mentioned in the context of this disorder. Affiliated tissues include liver, skin and eye, and related phenotypes are failure to thrive and splenomegaly

Disease Ontology : ¹² An intrahepatic cholestasis characterized by early onset of chronic unremitting cholestasis of hepatocellular origin that progresses to hepatic fibrosis, cirrhosis, and end-stage liver disease before adulthood.

KEGG : ³⁶ Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of rare, genetic autosomal recessive disorders characterized by unremitting cholestasis and progression to liver failure. The course of the disease involves portal hypertension, liver failure, cirrhosis, hepatocellular carcinoma along with several extra hepatic manifestations. The pathogenesis of PFIC revolves around defective bile acid synthesis, transport, and/or excretion.
