[Genome] exon number for Entrez gene

[Ann Zweig]

Hello Li,

	It depends on exactly what format your gene names are in.  If they look similar 
to this: GABRA3 (called the "Official Symbol" on the Entrez website), then you 
can just search for that name directly in the UCSC Genome Browser.  If your gene 
names are actually the "GeneID" (from the Entrez website) similar to this: 2556, 
then you will have to use the Table Browser on our website to convert them into 
UCSC Gene Names before proceeding.  You can use the knownToLocusLink table to do 
this conversion.

	Once you have located the gene in the Genome Browser, click directly on the 
annotation to go to the details page.  On this page you will see information 
about the number of exons and more.  Or you can visit the Table Browser to get 
the exact location of the exons.  Paste the list of gene names into the 
'identifiers' section, and output 'all fields' from the knownGene table.

	I hope this information is helpful to you.  Please don't hesitate to contact 
the mail list again if you require further assistance, or need more detailed 
instructions.


Regards,
