As of 2026-09-14

Mannan-binding lectin serine protease 2 shows late clinical disease relevance led by atypical hemolytic-uremic 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 O00187. Start with atypical hemolytic-uremic syndrome, then reuse UniProt O00187 as the stable protein anchor across project notes and exports.

Disease program
atypical hemolytic-uremic syndrome

Mannan-binding lectin serine protease 2 shows late clinical disease relevance led by atypical hemolytic-uremic syndrome. 3 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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