GET homology/id/:species/:id

Retrieves homology information (orthologs) by Ensembl gene id

Parameters

Required

NameTypeDescriptionDefaultExample Values
id String An Ensembl stable ID - ENSG00000173786
species String Species name/alias - homo_sapiens
human

Optional

NameTypeDescriptionDefaultExample Values
aligned Boolean Return the aligned string if true. Otherwise, return the original sequence (no insertions) 1 -
callback String Name of the callback subroutine to be returned by the requested JSONP response. Required ONLY when using JSONP as the serialisation method. Please see the user guide. - randomlygeneratedname
cigar_line Boolean Return the aligned sequence encoded in CIGAR format 1 -
format Enum(full, condensed) Layout of the response full -
sequence Enum(none, cdna, protein) The type of sequence to bring back. Setting it to none results in no sequence being returned protein -
type Enum(paralogues, projections, all) The type of homology to return from this call. Projections are orthology calls defined between alternative assemblies and the genes shared between them. Useful if you need only one type of homology back from the service all -
