As of 2026-09-14

GMP synthase [glutamine-hydrolyzing] shows late clinical disease relevance led by lupus nephritis. 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 P49915. Start with lupus nephritis, then reuse UniProt P49915 as the stable protein anchor across project notes and exports.

lupus nephritis

GMP synthase [glutamine-hydrolyzing] shows late clinical disease relevance led by lupus nephritis. 2 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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