As of 2026-09-14

Vitamin D3 receptor shows approved-linked disease relevance led by psoriasis. 5 more disease programs remain visible in the same review block. 7 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P11473. Start with psoriasis, then reuse UniProt P11473 as the stable protein anchor across project notes and exports.

Vitamin D3 receptor shows approved-linked disease relevance led by psoriasis. 5 more disease programs remain visible in the same review block. 7 linked drugs remain visible in the same block.

Start review with psoriasis because it currently carries approved-linked support. Linked drugs include BECOCALCIDIOL, CALCIPOTRIENE, CALCITRIOL, CHOLECALCIFEROL. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
