<p>Would you advice how to get promoter sequences for all or many human genes - in flat file(s) or by SQL query? I understand there can be multiple definitions for promoter region, but just anything universal would work.</p>

<p>My best bet would be to use BioMart's <a href='http://www.biomart.org/biomart/martview/'>Martview</a>, select a database, filter by the gene IDs you have (there are other ID options there too), and the use the sequence option in the attributes to determine which parts of the gene you want, be exon, intron, promoter, upstream, downstream, etc.</p>

<p>I used this tool to get many upstream regions for mouse genes using just NCBI's gene IDs as input.</p>
