### Description

This column displays the NCBI LocusLink ID associated with each gene, if available.

### Action

Click on the ID to display the NCBI LocusLink record. If LocusLink shows a link to the Online Mendelian Inheritance in Man (OMIM) -- represented by an orange square with an "O" inside it -- an OMIM record is available for the gene. OMIM is often an excellent source of human-curated information about human genes.
