+based on human data or making comparisons to patient-derived resources.  This
+requires converting genes between human and non-human analogues.  The
+babelgene R package provides predicted gene orthologs/homologs for frequently
+studied model organisms in an R-friendly tidy/long format.  The package
+integrates orthology assertion predictions sourced from multiple databases as
+compiled by the HGNC Comparison of Orthology Predictions (HCOP).")
