Chemical tractability of cohort targets
0 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) | 0 | |
| B | Phased (≥1) drug, not yet approved | 0 | |
| C | Druggable family + PDB, no drug | 0 | |
| D | Druggable family + AlphaFold only, no drug | 2 | ADAMTS10, ADGRE1 |
| E | Difficult family or no structure, no drug | 2 | MCOLN1, ARHGEF18 |
Undrugged target profiles
4 cohort genes are undrugged. Ranked by ‘starting-point quality’ (assay depth + drugged-partner adjacency).
