As of 2026-09-14

Intermediate conductance calcium-activated potassium channel protein 4 shows late clinical disease relevance led by sickle cell anemia. 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 O15554. Start with sickle cell anemia, then reuse UniProt O15554 as the stable protein anchor across project notes and exports.

Intermediate conductance calcium-activated potassium channel protein 4 shows late clinical disease relevance led by sickle cell anemia. 3 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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