Ensembl Rest API - GET homology/id/:id

Retrieves homology information (orthologs) by Ensembl gene id. DEPRECATED: use homology/id/:species/:id instead.

Parameters

Required

Name	Type	Description	Default	Example Values
id	`String`	An Ensembl stable ID	`-`	`ENSG00000157764`

Optional

Name	Type	Description	Default	Example 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`	`-`
compara	`String`	Name of the compara database to use. Multiple comparas exist on a server for separate species divisions	`vertebrates`	`vertebrates`
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`	`-`
target_species	`String`	Filter by species. Supports all species aliases	`-`	`human` `cow`
target_taxon	`Integer`	Filter by taxon	`-`	`9606` `10090`
type	`Enum(orthologues, 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`	`-`
