Journal ArticleDOI

TL;DR: PFIC associated with BSEP deficiency represents a previously unrecognized risk for HCC in young children and correlates well with demonstrable mutation in ABCB11.
Journal ArticleDOI
Severe bile salt export pump deficiency: 82 different ABCB11 mutations in 109 families.

TL;DR: With this study, >100 ABCB11 mutations are now identified and close surveillance of BSEP-deficient patients retaining their native liver, particularly those carrying 2 null mutations, is essential.
Journal ArticleDOI
The human bile salt export pump: characterization of substrate specificity and identification of inhibitors.
J A Byrne,Sandra Strautnieks,Giorgina Mieli-Vergani,Christopher F. Higgins,Kenneth J. Linton,Richard J. Thompson +5 more
TL;DR: The human BSEP is a high-affinity bile salt transporter and is competitively inhibited by therapeutic drugs, a potentially significant mechanism for drug-induced cholestasis.
Journal ArticleDOI

TL;DR: The genomic organization of ATP8B1 is reported and mutation analyses of 180 families with PFIC or BRIC that identified 54 distinct disease mutations are identified, including 10 mutations predicted to disrupt splicing, 6 nonsense mutations, 11 small insertion or deletion mutations, and 24 missense mutations.
Journal ArticleDOI

TL;DR: Clinical and laboratory features of disease in patients diagnosed with PFIC, who carried mutations in ATP8B1 (FIC1 deficiency) or ABCB11 (BSEP deficiency) were evaluated to identify features that distinguish presentation and course of these two disorders, thus facilitating diagnosis and elucidating the differing consequences of ATP 8B1 and ABCB 11 mutations.
