GET homology/symbol/:species/:symbol

Retrieves homology information (orthologs) by symbol

Parameters

Required

NameTypeDescriptionDefaultExample Values
species String Species name/alias - homo_sapiens
human
symbol String Symbol or display name of a gene - BRCA2

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 -
compara String Name of the compara database to use. Multiple comparas exist on a server for separate species divisions vertebrates vertebrates
external_db String Filter by external database - HGNC
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 - homo_sapiens
human
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 -
