Gene ID Mapping for Genotype-Tissue Expression (GTEx) Data

Convert 'Ensembl' gene identifiers from Genotype-Tissue Expression (GTEx) data to identifiers in other annotation systems, including 'Entrez', 'HGNC', and 'UniProt'.


grex offers a minimal dependency solution for mapping Ensembl gene IDs to Entrez IDs, HGNC gene symbols, and UniProt IDs, for Genotype-Tissue Expression (GTEx) data.

Install grex from CRAN:

install.packages("grex")

Or try the development version on GitHub:

# install.packages("devtools")
devtools::install_github("road2stat/grex")

To load the package in R, simply use

library("grex")

and you are all set. See the vignette (or open with vignette("grex") in R) for a quick-start guide.
