That isn't a very precise description of what you did. If I go to 
biomart.org, then choose GRCh37 as the dataset, then filter on HGNC 
symbol using VEGFC, then go to attributes, click the Sequences radio box 
and then choose Flank (Transcript), and check the Upstream flank box and 
enter 50 in the box to the right, I get the following sequence;


Which is identical to what I get from biomaRt, as well as Ensembl.

In addition, I don't see an 'export data' button on the left hand side 
of the biomart page. Is it possible that you are using something other 
than biomart.org?
