[Genome] Human Promoters

[Liron Levkovitz]

Hello,

I've downloaded the file upstream1000.zip of Human (hg18) and I've noticed
there are some promoters in the file with different RefSeq id's, but with
the same locations and therefore the same sequences (see example below).
What is the meaning of the different Id's?

Thanks
