Hello, Belinda.

What you are suggesting is possible by using our Table Browser.  If you are
unfamiliar with the Table Browser, please check out the User's Guide at
http://genome.ucsc.edu/goldenPath/help/hgTablesHelp.html.

To address your first question, for each particular gene locus, there may be
different isoforms, each with their own NM_XXXX number (RefSeq ID), so yes,
you would need to include all NM_XXXX numbers.  If you want information on
only a specific group of RefSeq IDs, the Table Browser gives you the ability
to specify a list of IDs.  Otherwise, the Table Browser gives you the
ability to specify the entire genome, a single chromosome or specific
regions on one or more chromosomes and it will give you a list of IDs that
occur in the regions you specify.

For your second question, follow these steps:

1. From http://genome.ucsc.edu, click "Tables" in the blue navigation bar at
the top of the screen.

2. Set the following:
Clade: Mammal
Genome: Human
Assembly: Feb. 2009 (GRCh37/hg19)
Group: Genes and Gene Prediction Tracks
Track: RefSeq Genes
Table: refGene
Region: Select "genome" for the entire genome.  Select "position" to specify
a single chromosome or region of a chromosome.  You can click the "define
regions" button to specify multiple regions or click the "paste list" or
"upload list" buttons to specify a list of RefSeq IDs.
Output format: Selected fields from primary and related tables

3. Click the "get output" button

4. Select the fields you are interested in.  If you're interested in exon
information for each gene, you might check name, exonCount, exonStarts and
exonEnds which will give you the RefSeq ID, number of exons and exon start
and stop positions for every RefSeq ID contained in your specified region.

5. Click the "get output" button to display your results.

You can experiment to find the set of options that works best for you.

In answer to your third question, the positions of the RefSeq genes aren't
necessarily identical between UCSC and NCBI or Ensembl, so please be aware
of that if you're working with data across sites.

I hope this helps!

Please contact us again at [email protected] if you have any further
questions.

Subject: [Genome] Question&Help

I've a list of genes to do a Target Sequencing and now I need to create a
list of NM_xxxxx number to give for the ''producion'' of capturing probes
for my genes/regions of interest.
However I have some questions concerning the NM_xxxx Numbers and also
concerning your site/UCSC.
1st question:
For each gene, do I need to introduce all the NM_xxxxx numbers corresponding
to each splice variant to be sure that all exons of all coding variants will
be captured?
2nd question (if yes for the 1st question):
How can you get the genomic coordinates of all the exons for all the splice
forms (variants) for a given gene ?
In UCSC, I can only get one cDNA at a time, getting the NM number for it,
but not including all exons (only the exons included in this particualr
cDNA). Is there a way of getting the coordinates for all the exons of one
gene, with a unique NM_xxxx number containing all exons ?
Or is an NM number restricted to one isoform ? In that case where can I find
the genomic coordinates of all the exons for one specific gene ???
Thank you very much for your (quick) help.
3rd question
If I use another database to obtain all the NM_xxxx number (p.e. NCBI,
ENSEMBL) does can be a problem for the genomic coordinates?
In other word cas I do the NM_xxxx number list for exemple with Ensembl and
after upload the list on UCSC and prepare the the file with all the genomic
coordinates?
Thank you very much for your help.
