Exporting homologues with BioMart

For a list of Ciona savignyi Ensembl genes, export the human orthologues.

ENSCSAVG00000000002, ENSCSAVG00000000003, ENSCSAVG00000000006, ENSCSAVG00000000007, ENSCSAVG00000000009, ENSCSAVG00000000011

Do all of these genes have a homologue in human?

Go to BioMart and click New. Choose the Ensembl Genes database. Choose the C.savignyi genes (CSAV 2.0) dataset.

Click on Filters in the left panel. Expand the GENE section by clicking on the + box. Enter the gene list in the Input external references ID list box. Gene stable ID(s) should be preselected.

Click on Attributes in the left panel. Select the Homologues attributes at the top of the page. Expand the GENE section by clicking on the + box. Deselect Gene stable ID version, Transcript stable ID and Transcript stable ID version. Expand the ORTHOLOGUES [F-J] section by clicking on the + box. Select Human gene stable ID.

Click Results. Select View: All rows as HTML.

All but ENSCSAVG00000000006 have a homologue in human.
