AB080. Genetic findings provide insight of biliary atresia patient complexity

Background Biliary atresia (BA) is a rare complex disease with unknown etiology. Current treatment of BA is Kasai portoenterostomy but is ineffective. BA is now the most common cause of pediatric liver transplantation worldwide. Characterize the disease complexity and stratify patients for personalized medicine is necessary. Genetic variants underlie BA pathogenesis and yet comprehensive genotype-phenotype correlations are yet to be investigated.
