We make a strong effort to use current NCBI official gene symbols and names in all our work, and we make much use of the excellent Bioconductor packages org.Mm.eg.db and org.Hs.eg.db for this purpose.
I have recently noticed that org.Mm.eg.db is giving incorrect official names for mitochondrial genes. It is giving human symbols for these genes instead of mouse symbols. For example
> mappedRkeys(org.Mm.egSYMBOL["17710"])  "COX3"
According to both Entrez Gene
the official symbol is "mt-Co3". This has been the official symbol for at least 4 years and probably longer.
The correct name is not even included as an Alias:
> mappedRkeys(revmap(org.Mm.egALIAS2EG)["17710"])  "COX3"
COX3 is the actually the symbol for the human ortholog. It should only be an alias for the mouse gene.
Same for all the mitochondrial genes. In all cases, org.Mm.egSYMBOL is giving the human symbol instead of the mouse symbol.
Is this deliberate? If not, can you please fix?
Thanks a lot
