Hi, Please take a look at PCDH15 in the genome browser: http://genome.ucsc.edu/cgi-bin/hgTracks?clade=mammal&org=Human&db=hg19&position=chr10%3A55580860-56561051
You can see that there are many transcripts for this gene, each with it's own id (e.g., uc010qhq.2, uc010qhr.2). I think maybe you're seeing more than one transcript. If that's not the case, please let me know how you are producing your output (what settings and steps in the Table Browser?). Make sure you're getting the transcript name (from knownGenes if you're using UCSC Genes) in your output. Please let us know if you have any additional questions: [email protected] - Greg Roe UCSC Genome Bioinformatics Group On 7/1/12 6:36 PM, Edge Edge wrote: > Dear Professor, > > Many thanks for your reply and explanation. > I just download again the desired output in BED format through UCSC. > However, I still feel a bit with the following case: > Case 1: > Gene Name Chromosome Start Position End Position Remarks > PCDH15 10 55568451 55569239 3'UTR > PCDH15 10 55568451 55569306 coding exons > PCDH15 10 55568502 55568819 intron > > It seems like PCDH15 is overlap based on UCSC output? > I can't really distinguish which regions is 3'UTR, coding exons or intron of > PCDH15. > > Case 2: > Gene Name Chromosome Start Position End Position Remarks > ATP5L 11 118279813 118280562 3'UTR > ATP5L 11 118279714 118280562 5'UTR > > It will be good if you can provide which some real case to distinguish > promoter region, 3'UTR, coding exons, 5'UTR and intron from the UCSC output > result. > > > Thanks for your advice regarding miRNA, rRNA, tRNA, etc. > I able to solve it out now. > > Looking forward to hear from you. > > best regards > Edge > > > > > ________________________________ > From: Brooke Rhead <[email protected]> > To: Edge Edge <[email protected]> > Cc: ucsc <[email protected]> > Sent: Saturday, June 30, 2012 11:31 AM > Subject: Re: [Genome] Help with extract rRNA, tRNA, 3'-UTR and 5'-UTR from > UCSC Genome Browser > > Hi Edge, > >> perfectly fine."
