Congenital Bile Acid Synthesis Defect (AKR1D1)
Congenital bile acid synthesis defect (AKR1D1-related) is an autosomal recessive disorder caused by pathogenic variants in the gene AKR1D1. This disorder is characterized by jaundice, intrahepatic cholestasis, fat-soluble vitamin malabsorption, steatorrhea, and hepatic failure. Disease progression is more rapid and severe in infancy, and without intervention, leads to liver cirrhosis and death, while individuals with the adult-onset form of the disease may experience splenomegaly, osteoporosis, and biliary tract abnormalities. Life expectancy information for this disorder is currently unavailable.
