As of 2026-09-14

Voltage-gated L-type calcium channel shows approved-linked disease relevance led by cardiovascular disease. 5 more disease programs remain visible in the same review block. 15 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt Q13936. Start with cardiovascular disease, then reuse UniProt Q13936 as the stable protein anchor across project notes and exports.

cardiovascular disease

Voltage-gated L-type calcium channel shows approved-linked disease relevance led by cardiovascular disease. 5 more disease programs remain visible in the same review block. 15 linked drugs remain visible in the same block.

Start review with cardiovascular disease because it currently carries approved-linked support. Linked drugs include BARNIDIPINE, BENIDIPINE, CILNIDIPINE, CLEVIDIPINE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
