For the HomoloGene release, see ?mmuhomology. I'm not sure if this was 
built using LL or Entrez Gene ids. Since it was built on 15 May, I think 
  Entrez Gene ids would have been used, but the URL for HomoloGene in 
?mmuhomology points to an old build that seems to use LL ids. Maybe Seth 
Falcon or Chenwei Lin can comment?
