In the latest edition of "Huh, I didn't expect that to work", our latest paper shows that LLMs can outperform existing methods for identifying causal genes in genome-wide association studies.

Large language models identify causal genes in complex trait GWAS
Identifying underlying causal genes at significant loci from genome-wide association studies (GWAS) remains a challenging task. Literature evidence for disease-gene co-occurrence, whether through automated approaches or human expert annotation, is one way of nominating causal genes at GWAS loci. However, current automated approaches are limited in accuracy and generalizability, and expert annotation is not scalable to hundreds of thousands of significant findings. Here, we demonstrate that large language models (LLMs) can accurately identify genes likely to be causal at loci from GWAS. By evaluating the performance of GPT-3.5 and GPT-4 on datasets of GWAS loci with high-confidence causal gene annotations, we show that these models outperform state-of-the-art methods in identifying putative causal genes. These findings highlight the potential of LLMs to augment existing approaches to causal gene discovery. ### Competing Interest Statement S.S., W.W., S.K., X.W., A.R., A.A., A.K., are employed by and hold stock or stock options in 23andMe, Inc. ### Funding Statement This study did not receive any funding ### Author Declarations I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.
