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

As of 2026-09-13

Sodium-dependent noradrenaline transporter shows approved-linked disease relevance led by attention deficit hyperactivity disorder. 5 more disease programs remain visible in the same review block. 16 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P23975. Start with attention deficit hyperactivity disorder, then reuse UniProt P23975 as the stable protein anchor across project notes and exports.

attention deficit hyperactivity disorder

Sodium-dependent noradrenaline transporter shows approved-linked disease relevance led by attention deficit hyperactivity disorder. 5 more disease programs remain visible in the same review block. 16 linked drugs remain visible in the same block.

Start review with attention deficit hyperactivity disorder because it currently carries approved-linked support. Linked drugs include AMPHETAMINE, AMPHETAMINE ASPARTATE, AMPHETAMINE SULFATE, AMPRELOXETINE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
