As of 2026-09-13

Arachidonate 5-lipoxygenase-activating protein shows late clinical disease relevance led by acute coronary syndrome. 3 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 P20292. Start with acute coronary syndrome, then reuse UniProt P20292 as the stable protein anchor across project notes and exports.

Disease program
acute coronary syndrome

Arachidonate 5-lipoxygenase-activating protein shows late clinical disease relevance led by acute coronary syndrome. 3 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

Start review with acute coronary syndrome because it currently carries late clinical support. Linked drugs include VELIFLAPON. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
