[Genome] question about double records in refseq database

[yael shemla]

Hi,

I would like to get your help about the refseq database:

1. The refseq databse should give deatils about full length transcript.
If so, why sometimes for the same gene (same genesymbol name) there are
several refseq records? is it alternative splicing forms? and if so, why
dont i get all the alternative splicing for all genes?

2. Why there are double records sometimes with the same refseq name?

3. I searched for the refseq  "NM_010699",on mouse genome  March2005.
when i enter the "NM_010699", i get details only about the
chr7:40932461-40940836 position
but when I search in this table with all the refseq in chr14, i get in the
list the NM_010699 gene.
why i don't get the two details when i search for the gene in the first
time?

Thanks a lot,
Yael.
