WebNov 22, 2024 · Recently, individuals lacking either functional Na +-taurocholate cotransporting polypeptide or organic solute transporter have been described, completing the quartet of bile acid transport deficiencies, as apical sodium–dependent bile acid transporter and bile salt export pump deficiencies were already known for years. Novel ... WebPFIC3 is caused by mutation of a closely related ABC transporter, ABCB4, which flops PC into the outerleaflet of the canalicular membrane. The flopped PC is extracted by the bile salts in the canaliculus to form a mixed micelle that reduces bile salt detergent activity.
