As of 2026-09-14

Glutamate NMDA receptor; GRIN1/GRIN2B shows clinical signal disease relevance led by depressive disorder. 5 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 Q05586. Start with depressive disorder, then reuse UniProt Q05586 as the stable protein anchor across project notes and exports.
