As of 2026-09-14

Estrogen receptor shows approved-linked disease relevance led by menopause. 5 more disease programs remain visible in the same review block. 9 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt Q92731. Start with menopause, then reuse UniProt Q92731 as the stable protein anchor across project notes and exports.

Disease program
menopause

Estrogen receptor shows approved-linked disease relevance led by menopause. 5 more disease programs remain visible in the same review block. 9 linked drugs remain visible in the same block.

Start review with menopause because it currently carries approved-linked support. Linked drugs include BAZEDOXIFENE ACETATE, ESTETROL, ESTRIOL, ESTROGENS, CONJUGATED. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
