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.
