Liver-restricted deletion of the biliary atresia candidate gene Pkd1l1 causes bile duct dysmorphogenesis and ciliopathy

Abstract excerpt

BACKGROUND AND AIMS: A recent multicenter genetic exploration of the biliary atresia splenic malformation syndrome identified mutations in the ciliary gene PKD1L1 as candidate etiologic contributors. We hypothesized that deletion of Pkd1l1 in developing hepatoblasts would lead to cholangiopathy in mice. APPROACH AND RESULTS: CRISPR-based genome editing inserted loxP sites flanking exon 8 of the murine Pkd1l1...
