No cohort gene has a CPIC/DPWG genotype-guided dosing guideline (PharmGKB).
Chemical tractability of cohort targets
30 approved/phased compounds have measured bioactivity against a cohort gene (and aren’t yet in disease-level trials). This is a research / tractability signal, NOT a therapeutic recommendation — a bioactivity row often reflects off-target or screening binding (e.g. promiscuous kinase inhibitors against a cohort kinase), implying no disease mechanism.

Druggability pyramid
Cohort genes binned by druggability tier (high → low):
| Tier | Definition | Genes | Symbols |
|---|---|---|---|
| A | Approved (phase 4 drug) | 2 | SCN2A, CHRNA4 |
| B | Phased (≥1) drug, not yet approved | 0 | |
| C | Druggable family + PDB, no drug | 0 | |
| D | Druggable family + AlphaFold only, no drug | 0 | |
| E | Difficult family or no structure, no drug | 3 | RTEL1, EEF1A2, RTEL1-TNFRSF6B |
Undrugged target profiles
3 cohort genes are undrugged. Ranked by ‘starting-point quality’ (assay depth + drugged-partner adjacency).
| Symbol | ChEMBL assays | Drugged partners (top 3) |
