Summary of gene unification results for NCBI (version 104), Ensembl (version 78), and Vega (version 58)

Genome features equivalent across all sources	23,174
Genome features unique to MGI	3095
Genome features unique to NCBI	12,719
Genome features unique to Ensembl	11,957
Genome features unique to Vega^a	0
Genome features requiring manual assessment (1:n, n:1, n:m categories)	>4000

^aThe data from Vega represent a subset of all possible genome annotations that are manually curated by the HAVANA team at The Sanger Institute. The annotations from Vega are included in the Ensembl annotation files. As a result, there are usually no annotations unique to Vega
