Pharmacogenomics
Cohort genes with a PharmGKB record: 4; with CPIC/DPWG dosing guidelines: 0.
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.
