Summaries for Biliary Atresia, Extrahepatic

OMIM : 57 Biliary atresia is a disorder of infants in which there is progressive obliteration or discontinuity of the extrahepatic biliary system, resulting in obstruction of bile flow. Untreated, the resulting cholestasis leads to progressive conjugated hyperbilirubinemia, cirrhosis, and hepatic failure (Bates et al., 1998). Most patients require liver transplantation within the first year of life (Leyva-Vega et al., 2010). See also Alagille syndrome (118450), which includes biliary atresia as a feature. (210500)

MalaCards based summary : Biliary Atresia, Extrahepatic, also known as isolated atresia of bile ducts, is related to biliary atresia and cholestasis, and has symptoms including icterus An important gene associated with Biliary Atresia, Extrahepatic is GPC1 (Glypican 1). The drugs Meloxicam and Anti-Inflammatory Agents have been mentioned in the context of this disorder. Affiliated tissues include liver, bone and brain, and related phenotypes are hepatomegaly and cirrhosis
