As of 2026-09-13

Nitric oxide synthase, inducible shows clinical signal disease relevance led by migraine disorder. 2 more disease programs remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P35228. Start with migraine disorder, then reuse UniProt P35228 as the stable protein anchor across project notes and exports.

Disease program
migraine disorder

Nitric oxide synthase, inducible shows clinical signal disease relevance led by migraine disorder. 2 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

Start review with migraine disorder because it currently carries clinical signal support. Linked drugs include GW-274150. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
