(mouse) Convert hugo symbol (i think) to Ensembl ID

Question

[Wesley]

I am trying to convert these gene symbols( that's what i think they are) to ensembl ID's using biomaRt package. But for some reason it seems to fail. Would love to have some feedback!

library(biomaRt)

ensembl <- useMart("ensembl", dataset="mmusculus_gene_ensembl")

genes <- c("Acad11","Acad8", "Acad9","Acadm","Acadsb", "Acan" ,"Acap1","Acap2" ,"Acat1","Acbd3", "Acbd4")

foo <- getBM(attributes=c('ensembl_gene_id',
                          'external_gene_name'),
             filters = 'hgnc_symbol',
             mart = ensembl,
             values = genes)

Thanks in advance.

Almost correct but it must be mgi_symbol instead of hgnc_symbol since the HGNCs represent human genes. MGI is the equivalent for mouse. By the way it is Ensembl not Ensemble, just saying if you ever write this up as a paper be sure to correctly spell the data sources ;-)

library(biomaRt)

ensembl <- useMart("ensembl", dataset="mmusculus_gene_ensembl")

genes <- c("Acad11","Acad8", "Acad9","Acadm","Acadsb", "Acan" ,"Acap1","Acap2" ,"Acat1","Acbd3", "Acbd4")

foo <- getBM(attributes=c('ensembl_gene_id',
                          'external_gene_name'),
             filters = 'mgi_symbol',
             mart = ensembl,
             values = genes)

> foo

Hi Wesley,

Since you are querying the mouse genes, you need to use the 'mgi_symbol' filter with your list of gene names.
