Scott, Gene symbols and other IDs are case sensitive. For mouse and rat, most OFFICIAL gene symbols are initial upper case only, while all upper cases for human and many other species. For example, some mappable gene symbols (from your list) for mouse would be like Cd74, Mgp and Cd52, while they should be CD74, MGP and CD52 for human. You may tried gene symbol search at NCBI like http://www.ncbi.nlm.nih.gov/gene/?term=CD52 and look at the results for different species.

Below shows what I did.? The variable ?T? holds the data, and I do a map, but none of the genes get mapped to entrez gene ids.? However, if I use human (?Hs?) then it works.?
