Benign Recurrent Intrahepatic Cholestasis with a Single Heterozygote Mutation in the ATP8B1 Gene / 대한소아소화기영양학회지

ABSTRACT

Benign recurrent intrahepatic cholestasis (BRIC) is a rare autosomal recessive inherited disorder characterized by multiple recurrent episodes of severe cholestatic jaundice without obstruction of extrahepatic bile duct. We present the case of a 7-year-old boy with BRIC confirmed by mutation analysis in the ATP8B1 gene and typical clinical manifestation. Despite inheritance of BRIC, we detected a mutation on only one allele. To our knowledge, this is the first report of BRIC with a confirmed single heterozygote novel mutation in the ATP8B1 gene in Korea.
