Genotype-Tissue Expression (GTEx) Project

The Genotype-Tissue Expression (GTEx) Project is a research initiative that studies how genetic differences influence the way genes are active in various human tissues. By examining tissue samples from many individuals, GTEx helps scientists understand how genetic variations affect health, disease, and traits. This work enables better insights into personalized medicine, allowing treatments to be tailored based on how individuals' genes function across different parts of the body.
