Structured disease, protein, and project context should read before the lower-level identity rail.

As of 2026-09-13

Ileal sodium/bile acid cotransporter shows approved-linked disease relevance led by intrahepatic cholestasis. 5 more disease programs remain visible in the same review block. 4 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt Q12908. Start with intrahepatic cholestasis, then reuse UniProt Q12908 as the stable protein anchor across project notes and exports.

Disease program
intrahepatic cholestasis

Ileal sodium/bile acid cotransporter shows approved-linked disease relevance led by intrahepatic cholestasis. 5 more disease programs remain visible in the same review block. 4 linked drugs remain visible in the same block.

Start review with intrahepatic cholestasis because it currently carries approved-linked support. Linked drugs include LINERIXIBAT, ODEVIXIBAT, ODEVIXIBAT SESQUIHYDRATE, VOLIXIBAT. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
