[ensembl-dev] Many Ensembl-Ids lack annotation?

[Colin Davenport]

Dear Ensembl users,

firstly, congratulations. Ensembl is a nice resource which we don't have in
the bacterial world!

I have a question about some very highly expressed genes which are lacking
annotations in the current Ensembl database v62.

I am using the edgeR bioconductor package to analyse human RNA-seq data.
Some of the most important genes in the dataset
have Ensembl IDs, but no annotation attached (see examples below,
eg. ENSG00000257107).

Are these old, too new or am I missing something here?

If I look up the gene on the Ensembl website I get. (IDHistory_gene)
Ensembl gene ENSG00000257107 is no longer in the database and has not been
mapped to any newer identifiers

In fact, the edgeR ensembl database has about 52000 entries, but the bioMart
export only gives me about 22000 entries with annotation.
Surely at least the important highly expressed genes must have been mapped
to other identifiers if they have been removed ?




Thanks for any help!
Regards,
Colin
