As of 2026-09-14

Somatostatin receptor type 3 shows approved-linked disease relevance led by acromegaly. 3 more disease programs remain visible in the same review block. 2 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P32745. Start with acromegaly, then reuse UniProt P32745 as the stable protein anchor across project notes and exports.

Somatostatin receptor type 3 shows approved-linked disease relevance led by acromegaly. 3 more disease programs remain visible in the same review block. 2 linked drugs remain visible in the same block.

Start review with acromegaly because it currently carries approved-linked support. Linked drugs include PASIREOTIDE DIASPARTATE, PASIREOTIDE PAMOATE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
