[ensembl-dev] Bug?? Biomart mapping of Mouse ID to MGI ids

Hi Ashok,

MGI mappings, like HGNC mappings, are direct mappings we import directly 
from the source.
According to this database, both Ugt2a1 and Ugt2a2 map to the Ensembl gene.
http://www.informatics.jax.org/marker/MGI:2149905
http://www.informatics.jax.org/marker/MGI:3576095

Looking at the gene models, there is an overlap with ENSMUSG00000106677, 
which corresponds to Ugt2a1.
I suspect MGI:2149905 needs to be updated to link to ENSMUSG00000106677 
instead of ENSMUSG00000029268, but we cannot change it at our end.
If you have any experimental evidence to correct those mappings, please 
contact MGI (mgi-help at jax.org) to let them know.


Regards,
Magali
