As of 2026-09-14

Sarcoplasmic/endoplasmic reticulum calcium ATPase 2 shows clinical signal disease relevance led by congestive heart failure. 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 P16615. Start with congestive heart failure, then reuse UniProt P16615 as the stable protein anchor across project notes and exports.

congestive heart failure

Sarcoplasmic/endoplasmic reticulum calcium ATPase 2 shows clinical signal disease relevance led by congestive heart failure. 2 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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