Dear All
I just downloaded a refseq exon table (BED format) from UCSC table browser. I notice that the exon coordinates are not unique in the table. For example, in the following case, the exon start and end coordinates are all the same, but the gene IDs are different. Does it mean different genes or different isoforms?
Also, in this following case,
the exon end coordinate for the last one is different from the other two. The gene IDs also differ. What does this mean?
All your help will be appreciated.
