Clinical Comment

Cholestasis is defined as a decrease in bile flow due to impaired secretion by hepatocytes or obstruction of bile flow by intra- or extrahepatic bile ducts. The clinical definition of cholestasis is any condition in which substances normally secreted into the bile are retained. The mechanisms of cholestasis can be broadly divided into hepatocellular, in which impairment of bile formation occurs, and obstructive, in which obstruction of bile flow occurs after its formation. Accumulation of bile acids leads to pruritus, hepatocyte toxicity, and cirrhosis. Neonatal cholestasis includes a variety of different disorders, several of which are caused monogenically. Progressive familial intrahepatic cholestasis accounts for more than 15% of neonatal cholestasis syndromes and approximately 15% of liver transplants in childhood. Using a large targeted gene panel for infants with cholestasis after exclusion of biliary atresia, more than 80% of infants received a diagnosis of monogenic etiology. Although affected individuals typically develop liver failure before adulthood, cases with later onset can be differentiated by comprehensive DNA studies. Most monogenic cholestatic disorders are inherited in an autosomal recessive manner. DNA diagnostic yield, by its very nature, depends critically on prior clinical case workup. But a negative molecular genetic result does not constitute exclusion of the clinical diagnosis.
