The GTEx Biospecimen Collection Infrastructure. The GTEx Biospecimen Source Sites were responsible for donor recruitment, tissue procurement and processing, and data collection. Brain and hair samples were sent to the Miami Brian Bank for quality control purposes, coronal sectioning of brain tissue, and storage of brain tissue. The Comprehensive Biospecimen Resource handled biospecimen receipt, processing, distribution and storage, histology and imaging, and kit development and production. The Comprehensive Data Resource is a data repository that served as an honest broker to keep limited data set information confidential and distribute de-identified data. The Pathology Resource Center performed case review through tissue identification and quality assessments. The Laboratory, Data Analysis, and Coordinating Center conducted molecular and data analysis as well as served as a project management and data-coordinating center. Clinical, demographic, handling, genetic and molecular data from GTEx biospecimens can be accessed through the National Center for Biotechnology Information's database of Genotypes and Phenotypes.
