Cohort genes with ChEMBL bioactivity (full, sorted by assay count)
| Symbol | Assays | Type breakdown |
|---|---|---|
| DOCK1 | 1 | Binding:1 |
Pharmacogenomics
Cohort genes with a PharmGKB record: 6; with CPIC/DPWG dosing guidelines: 0.
No cohort gene has a CPIC/DPWG genotype-guided dosing guideline (PharmGKB).
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 | 0 | |
| E | Difficult family or no structure, no drug | 6 | SGCA, SP4, TSPAN9, BAHCC1, DMD, DOCK1 |
Undrugged target profiles
6 cohort genes are undrugged. Ranked by ‘starting-point quality’ (assay depth + drugged-partner adjacency).
