Multiple OMIM IDs

Since some of our symbols can link to more than one OMIM entry, you may find that some symbol reports now have multiple OMIM cross reference (i.e IGH) when in the past we displayed one. This change has also affected the “Complete HGNC Dataset” download file (available on our Statistics & Downloads page) in that the omim_id column in the tab separated file may have multiple OMIM IDs separated by a comma and space (i.e ‘, ‘). This is also applicable to the data downloaded from our Custom Downloads application when returning OMIM IDs.
