Ensembl stable IDs

Ensembl annotation uses a system of stable IDs that have prefixes based on the species scientific name plus the feature type, followed by a series of digits, e.g. ENSG00000139618.

Ensembl's stable identifiers are mapped between re-annotation processes using a combination of location based mappings and those generated by Exonerate. The process performs exon based mapping and deriving subsequent identifier mappings based upon these findings. Stable identifiers can also be versioned depending upon the presence of change between an old and new entity deemed similar enough to have the identifier transfered. These rules are elaborated in our stable id versioning document.

The prefixes in current use are:

Feature prefixes

E exon
FM protein family
G gene
GT gene tree
P protein
R regulatory feature
T transcript
