Genotype-Tissue Expression (GTEx)

The Genotype-Tissue Expression (GTEx) project is a research effort that studies how genetic differences influence gene activity in various human tissues. By examining samples from different organs like the heart, brain, and liver, GTEx helps scientists understand how our DNA variations affect health and disease. This information is valuable for identifying why certain conditions develop and for developing personalized treatments. Overall, GTEx provides a comprehensive map of gene expression across different tissues, linking genetics to tissue function and health outcomes.
