![]() Requesting AccessĪccessing the raw data requires authorization from the NIH database of Genotypes and Phenotypes (dbGaP). However, due to the nature of our donor consent agreement, raw data and attributes which might be used to identify the donors, such as raw sequencing data or variant calls, are not publicly available on the GTEx Portal. The GTEx Portal provides open access to data including gene expression, QTLs, and histology images. The primary entry point for accessing GTEx data is through the GTEx portal ( ). ![]() It also features an image library of the tissue samples, and a form to request tissue samples. To provide insight into how genes are expressed differently across the body and how they are regulated, GTEx includes whole-genome sequence and RNA-sequence from nearly 1000 deceased adult donors, with multiple tissue samples collected per donor (e.g. However, it is less clear how these variants affect gene expression and thereby contribute to human diseases. Previously, large genetic studies identified variants that are associated with human diseases. ![]() The Genotype-Tissue Expression (GTEx) Program is a widely used data resource and tissue bank to study the relationship between genetic variants (inherited changes in DNA sequence) and gene expression (how genes are turned on and off) in multiple human tissues and across individuals.
