Convert CD (cluster of differentiation) into gene symbol I want to convert names according to the "cluster of differentiation" nomenclature into accepted gene symbols. For example, CD3 should map to "CD3a;CD3b;CD3c;CD247" and "CD45RO" should map to "PTPRC". If the surface antigen isn't coded for by a gene, it should map to "" or something similar. 

I've seen Obtain CD (cluster of differentiation) marker expression information, but the Abcam table used there does not give the gene symbol -- it gives a list of alternate names. I've seen table 1 of this paper, but it contains errors -- for example, TNFRSF11 should be TNFRSF11A. I could copy this table by hand, or I could download this one, though that's annoying because it doesn't have one row per CD. 

Is there a canonical (or just a convenient and reliable) way to do this?
I ended up using option 4 and parsing the columns for "Synonym" and "Previous Symbol".
