Hello, Jennifer,
Thanks for your question. The OMIM tables are not accessible via the Table
Browser if you have "genome" selected as a region, per our agreement with
the OMIM team not to redistribute their entire dataset. The DDX11L1 gene
in your output is the first gene on chr1 and your output is likely very large
(whole genome)? Choose the button next to "position" to restrict your query
to the chr3 region you were viewing on the Browser. The OMIM tables should
then be available to you.
The multiple entries are due to the fact that the knownGene table will give a result
for each isoform. If you wish one isoform per locus, use the knownCannonical
table in the UCSC Genes track. Though I see in your image that you already
have that table selected, your output shows that the query you executed for that
particular output had the knownGene table selected.
The following video shows most of the process you request:
You may also be interested in the Data Integrator, which can do what the
Table Browser does but also a bit more. Here is a short video demonstrating
almost the exact problem you describe, including obtaining OMIM data:
Best wishes, and thanks for using the Genome Browser.
