Genomic analysis of model organisms frequently requires the use of databases based on human data or making comparisons to patient-derived resources. This requires harmonization of gene names into the same gene space. The babelgene R package helps to simplify the conversion process. It provides gene orthologs/homologs:
You can install the babelgene R package from CRAN.
install.packages("babelgene")Load babelgene.
library(babelgene)The main functionality is accessed via the orthologs()
function which takes one or more genes and outputs a data frame of
predicted ortholog/homolog pairs. The output data frame contains gene
symbols and IDs for human and the specified species. Several examples
are provided below.
Get mouse equivalents for a set of human genes.

species parameter to be set (both scientific and common

with the help of the species() function.

The HGNC Comparison of Orthology Predictions (HCOP) integrates the orthology assertions predicted for human genes by eggNOG, Ensembl Compara, HGNC, HomoloGene, Inparanoid, NCBI Gene Orthology, OMA, OrthoDB, OrthoMCL, Panther, PhylomeDB, TreeFam and ZFIN.
The name babelgene is derived from the Babel Fish, a fictional species of fish that could translate for humans.
These binaries (installable software) and packages are in development.
