As of 2026-09-14

P2X purinoceptor 7 shows clinical signal disease relevance led by rheumatoid arthritis. 3 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 Q99572. Start with rheumatoid arthritis, then reuse UniProt Q99572 as the stable protein anchor across project notes and exports.

Disease program
rheumatoid arthritis

P2X purinoceptor 7 shows clinical signal disease relevance led by rheumatoid arthritis. 3 more disease programs remain visible in the same review block. 2 linked drugs remain visible in the same block.

Start review with rheumatoid arthritis because it currently carries clinical signal support. Linked drugs include AZD9056, CE-224535. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
