As of 2026-09-13

High affinity cGMP-specific 3',5'-cyclic phosphodiesterase 9A shows clinical signal disease relevance led by Alzheimer disease. 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 O76083. Start with Alzheimer disease, then reuse UniProt O76083 as the stable protein anchor across project notes and exports.

Alzheimer disease

High affinity cGMP-specific 3',5'-cyclic phosphodiesterase 9A shows clinical signal disease relevance led by Alzheimer disease. 5 more disease programs remain visible in the same review block. 2 linked drugs remain visible in the same block.

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