Why Are There Duplicate Refseq Entries Mapping To Identical Genome Locations?
I know refseq may duplicate gene IDs if they map to multiple regions on the genome.
This is different - I'm finding duplicates even for genes which map to _identical_ regions on the genome. For example, this query for chr1:77548961-77812107 on the most recent rnor5 genome returns two results:
The two results are exactly identical. Why is this?

This looks like a bug at UCSC- if you view the RefSeq annotation you only see this once: http://tinyurl.com/ngpwts3 I'd recommend reporting this to UCSC to try to find out more.
