Pathway analysis

Distinct Reactome pathways touched by cohort: 10. Enrichment computed across 10 evidence-associated genes (9 with Reactome annotation).

Pathways by enrichment

Over-representation of cohort genes vs the genome-wide background (hypergeometric test, Benjamini-Hochberg FDR; fold = observed/expected over 9 annotated cohort genes). Counts and members are kept as ground-truth; sorted by enrichment.

Chemical tractability of cohort targets

16 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.
