In the UCSC Genome Browser http://genome.ucsc.edu/cgi-bin/hgGateway first select your region, then select "Tables" and select the "positions" in "region" choosing "Known Genes" as "table".

In BioMart http://www.ensembl.org/biomart you can select your region defining the chromosome and coordinates adding as much information as you need.

Lots of options, UCSC browser probably leading the list. I also like to use GEDI. If you enter your region in "coordinate search" multiple annotations from multiple sites are pulled for you, including from UCSC. Sort of one-stop shopping for annotations.

I'd suggest giving the tools on the Galaxy server a try.

Hello Ezhil, you can try this online annotation tool http://cru.genomics.iit.it/AnnotateGenomicRegions/annotate.jsf Luca
