This workflow retrieves information about SNPs which are associated with a given
Affymetrix probe set Id via its EMBL accession number.  Specifically, it queries the
HGVBASE databank to select HGVBASE Ids which are associated with an EMBL 
accession number.

The results for Affymetrix probe set Id, 1001_at, are:
