As of 2026-09-12

Sodium-dependent serotonin transporter shows approved-linked disease relevance led by major depressive disorder. 5 more disease programs remain visible in the same review block. 19 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P31645. Start with major depressive disorder, then reuse UniProt P31645 as the stable protein anchor across project notes and exports.

Disease program
major depressive disorder

Sodium-dependent serotonin transporter shows approved-linked disease relevance led by major depressive disorder. 5 more disease programs remain visible in the same review block. 19 linked drugs remain visible in the same block.

Start review with major depressive disorder because it currently carries approved-linked support. Linked drugs include CITALOPRAM HYDROBROMIDE, DESVENLAFAXINE, DESVENLAFAXINE FUMARATE, DESVENLAFAXINE SUCCINATE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
