No cohort gene has a CPIC/DPWG genotype-guided dosing guideline (PharmGKB).

Drug repurposing candidates

0 approved/phased drugs hit cohort targets but don’t yet appear in disease-level clinical trials. Target-inhibition rationale is strongest for cancer driver genes; a bioactivity hit is a screening signal, not a treatment claim.
