Hi, Mark,

AnnBuilder retrieves chromosome location data from UCSC Genome Browser. You 
can query UCSC Genome Browser directly or download data from 

biomart (BioMart and biomaRt) queries data from Ensembl (along with other 
databases). There are some collaborations between Ensembl and UCSC. I am sure 
others on the list can help you out on this part.
