We find
🧬 Existing methods perform poorly on PerturbQA ❌
🧬 Naively applying LLMs also performs poorly ❌
🧬 Simple reasoning template + retrieving experimental outcomes = does ok ✅
🧬 LLMs easily summarize gene sets ✅
🧬 Still a long way to go! ✨

🧬 Existing methods use knowledge graphs to relate seen vs. unseen perturbations. It seems wrong that current GNNs discard the semantics of knowledge graphs
🧬 Language may be useful for harmonizing these diverse information

We propose
🧬 PerturbQA: a new benchmark for perturbations + LLM reasoning for biomolecular discovery.
🧬 Perturbation experiments should be modeled at the granularity of statistical insights. Goal = predict differential expression / characterize gene sets
