Genotype-Tissue Expression Project (GTEx)

Pathology and Biorepository Core

Launched by the National Institutes of Health (NIH) in September 2010, the Genotype-Tissue Expression (GTEx) Project created a resource that scientists can use to study how an individual’s genetic makeup affects tissue-specific gene expression. The end result was a database and a tissue bank that are available to researchers around the world.

VARI’s Pathology and Biorepository Core served as the caHUB Comprehensive Biospecimen Resource for the GTEx Project and provided biospecimen collection kit production, distribution and tracking, biospecimen receipt, handling and storage, and biospecimen processing (PAXgene processing and embedding, slide creation and digitization).

The GTEx collection phase has ended and the legacy specimens have been transferred to the Broad Institute for future distribution. For further information on this collection including access requests to legacy biospecimens, see the GTEx Portal.
