Scope

gtexr wraps the Genotype-Tissue Expression (GTEx) Portal API (v2), providing a simple option for programmatic data retrieval from this rich resource.

GTEx data is extensively used across diverse areas of biomedical research, from basic regulatory genomics to clinical applications. For example, researchers use GTEx to investigate tissue-specific gene expression patterns, interpret genome-wide association study findings, and infer causal relationships between gene expression and disease. While the GTEx Portal provides a web interface for data access, many analyses require programmatic access to query multiple genes, variants, or tissues systematically.

There are no other similar R packages on CRAN (and no Python packages on PyPI that I have found). I am aware of the R package gtexRNA on GitHub from sigven, however it appears this was not completed, is no longer actively maintained, and was designed to query the now discontinued GTEx API V1.
